Respond to the following based on your reading.
1. Name the three common states of matter on earth.
2. Which states of matter have a set shape? Explain why this is, based on the
а
animations you observed for the different states of matter.
3. Which states of matter have a set volume? Explain why this is, based on the
animations you observed for the different states of matter.
4. The boiling point is the temperature at which a liquid substance will turn to
vapor, and also the temperature at which vapor will condense to a liquid. The
a
boiling point of ethanol is about 80°C, and the boiling point of water is about
100°C.
a. What can you conclude about the intermolecular forces in water and
ethanol?
b. Do you predict water freezes at a higher temperature or at a lower
temperature than ethanol?
5. Recall how different Van der Waals attractions and how ionic charges changed
the movement of atoms in the animation. Do you think that Van der Waals
attractions or ionic charges are stronger? Why?
Answer:
Most people are familiar with three states of matter – solids, liquids and gases – but there are two more that are less commonly known but just as important – plasmas and Bose-Einstein condensates. They are very compressible (particles are widely spaced). There are three states of matter: solid; liquid and gas. They have different properties, which can be explained by looking at the arrangement of their particles.
atoms
An atom is the smallest particle of an element, having the same chemical properties as the bulk element. The first accurate theory explaining the nature of matter was Dalton's Atomic Theory: 1. All matter is composed of atoms, and atoms are indivisible and indestructible.
What are the 8 states of matter?
Bose–Einstein condensate.
Fermionic condensate.
Degenerate matter.
Quantum Hall.
Rydberg matter.
Rydberg polaron.
Strange matter.
Superfluid
Answer:
1. Liquid, Solid, Gas
2. Solid has a set shape. Solid can move but gas and liquid is more flexible than solid.
3. Solid has a fixed volume while liquid and gas takes the volume of its container. Solid stays in one place while gas and liquid are flexible.
4. A. The stronger the intermolecular forces in a liquid the higher the boiling point. Therefore, water has a stronger intermolecular force than ethanol.
B. Water molecules are more attracted to each other than ethanol (alcohol) molecules, because water has more hydrogen atoms bonded to oxygen. ... So, that's why alcohol has a much lower freezing point
5. Ionic charges are stronger.
Covalent bonds are known to have the strongest and most stable bonds since they go deep and into the inter-molecular state. A diamond is an example of a compound with this characteristic bond.
Ionic bonds are the next strongest molecular bond following covalent bonds. This is due to the protons and electrons causing an electro-static force which results to the strong bonds. An example would be Sodium Chloride (NaCl), which when separated is Na⁺ and Cl⁻.
Van der Waals forces, also known as Dispersion forces, are the weakest type of molecular bonds. They are only formed through residual molecular attractions when molecules pass by each other. It doesn't even last long due to the uneven electron dispersion. It can be made stronger by adding more electrons in the molecule. This kind of molecular bonds appear in non-polar molecules such as carbon dioxide.

You have a friend who became stranded in a blizzard without food for
several weeks. This friend, when rescued, had lost about 7 kg (about 15
Ibs). As he was quite healthy to begin with, he assumed the weight he
lost was stored fat, but he wondered where the fat had gone, How did
the fat leave his body?
The fat didn't really leave his body. Fat was converted to glucose in the gluconeogenesis pathway to give him energy during the period of starvation.
Fat is stored in the body in the adipose tissue. Fat plays so many roles in the body such as;
Protection of vital organsInsulating the body from coldServing as an energy storeIn times of starvation, fact could also be broken down to release energy. This occurs when fat is broken down to glycerol and fatty acids. When this occurs, glycerol goes to the liver where it is converted to glucose in the gluconeogenesis pathway. This helps to produce energy in times of starvation thereby depleting the body's fat reserve.
As this process occurs, the fat reserve in my friend's body kept going down resulting in his loss of about 15 Ibs of weight.

Atoms with full valence electron shells are chemically stable. Most noble gases have eight valence electrons. So, one model for chemical bonding is the octet rule. This states that atoms will _________ or __________ electrons in order to reach the more stable arrangement of eight electrons in their valence shells. A) lose, gain B) conduct, share C) transfer, share D) conduct, transfer
Answer:
A - Gain or Lose
Explanation:
Atoms with full valency electron shell are usually very stable. Most noble gases with full valency shell are usually very stable . The valency electron are fully occupied(8) for all noble gases this is what makes them hard to react with other element.
During chemical bonding elements strife to attain the octet rule. The octet rule is to have a full valency electron through bonding . When this atom bond they either transfer electron or share electrons.
The case of transferring electrons forms an ionic bonding. One atom gain electrons while the other lose electrons during ionic bonding. One atom form cation while the other forms anions.
For covalent bonding atoms are shared to attain the octet rule. This kind of bonding exist between a non metal and another non metals
Answer:
Explanation:A: gain or lose

Which object is hotter in terms of its kinetic energy: the cup of coffee or the iceberg? Explain the reason for your answer in terms of your understanding of the kinetic molecular theory of matter.
Answer:
red-hot iron bar
Explanation:
An iceberg could even contain more heat energy than a cup of coffee or a red-hot iron bar. That's because its bigger and contains so many more molecules, each of which has some heat energy. The coffee and the iron bar are hotter (have a higher temperature), but the iceberg holds more heat because it's bigger.

Explain how a lack of carbohydrates will impact cellular functions and why?
Answer:
Carbohydrates they say is the major classes of food and don't forget they are stored by stach in the body and gives your body energy
Carbohydrates are degraded into sugar which, as a primary source, is required for the brain, muscles and other parts of the human body to function normally.
When you don't get enough carbohydrates, the level of sugar in your blood may drop to below the normal range (70-99 mg/dL), causing hypoglycemia.

Imagine you have been shipwrecked and are floating on a small piece of wood in the middle of the ocean. You are terribly thirsty and take a drink of seawater (3.5% salt). What do you think happens to your stomach cells (1% salt), and why?
Given the higher salinity of the ocean water in comparison to your stomach cells, you will lose water from your cells and become dehydrated.
Osmosis is a phenomenon that shows that in the presence of a space in which the solute concentration is higher than its current location, water will travel towards that more concentrated space in an attempt to dilute the concentration.
The urge to drink is what we call being thirsty. This urge has a biological origin. It is the body's way of telling you that your cells need more water, which leads us to often consume any water we have available. This is not always in our best interest.
However, due to osmosis, drinking the seawater would only have a negative effect on your stomach cells. As stated in the question, the cells contain less concentration of solute (in this case salt) than the water. This means that instead of entering the cell, water would leave to dilute the new seawater, thus dehydrating you more and worsening your condition.

I. Developmental dysfunction
II. Gender imbalances
III. Increased reproduction rates
I, II, and III
I and II

The release of toxins such as heavy metals into the water bodies has been deeply frowned at .This is because toxins usually have a negative effect on aquatic species. The negative effects include:
Developmental dysfunctionGender imbalancesToxins also gives rise to developmental dysfunction in the animals . The toxins ensures that there is a shortage by interfering/reacting with the nutrient needed for the growth of these organisms.
The issue of gender imbalance is also true as some toxins causes water bodies to be warmer which favors the presence of female aquatic species such as reef fish.
Toxins causes aquatic bodies to be short of oxygen supply as the elements or compounds released vie for oxygen with the animals which may lead to less reproduction rates and death in severe occasions.

HELP PLEASE!!!explain how Earth is heated through conduction
As it's known conduction needs a medium for heat transfer and during the day, sunlight rays pass through the Earth's atmosphere and near the earth's surface is where most heat transfer by conduction occurs since air is a poor conductor. Thus, the sunlight hits the earth's surface(ground) and in turn heats the air above it and transfering the heat.
It must be known that conduction happens mostly near the earth's surface.
Answer:
Conduction is one of the ways that energy is transferred from the earth's atmosphere to the air. Conduction is the process by which heat energy is transmitted through collisions between neighboring molecules. Think of a frying pan set over an open camp stove.
