Which of the following has the most thermal energy?
A full-size candy bar that is melting
A swimming pool on a sunny day
The entire atmosphere of the earth
1 gallon of boiling water
The one that has the most thermal energy out of the following is 1 gallon of boiling water.
Thermal energy is the energy generated by a material as a result of particle movement inside the material. Thermal energy causes things to have an internal temperature, which may be measured. The greater the temperature measured, the quicker the particles travel within the system.
The full-size candy bar that is melting melts at a slower particle rate compared to the 1 gallon of boiling water whose particles travel faster.
A swimming pool on a sunny day has average thermal energy. Also, the entire atmosphere of the earth may not experience the same amount of thermal energy from the sunlight.
Therefore, we can conclude that the most thermal energy out of the following is 1 gallon of boiling water.

which scientist surmised the scientific principle that the position and momentum of an electron cannot be known simultaneously with a high degree of accuracy?
The scientific principle was surmised by Werner Heisenberg and it is called Heisenberg's uncertainty principle.
In 1927 German scientist Werner Heisenberg propounded the uncertainty principle which states that both the position and momentum of a particle cannot be measured simultaneously with certainty.
That is, the more accurate we measure the position of the particle, the less accurate we would measure its momentum.
Heisenberg's uncertainty principle is stated mathematically as ΔpΔx ≥ h/4π where p is the momentum, x is the position and h is Planck's constant.
So, the scientific principle was surmised by Werner Heisenberg and it is called Heisenberg's uncertainty principle.

Im doing a science project and need examples and non-examples of an Atom. some examples of an atom is neon, hydrogen, argon, etc so I got that part. But what are some non-examples of an atom and why?
Answer:
Anything not on the periodic table is an element non example! ... So, for a substance to be an element, all of its atoms must have the same number of protons. Examples of elements include hydrogen, lithium, nickel, and radium.
Explanation:
Non-examples of an atom refer to entities that are not considered atoms.
Molecules consist of two or more atoms chemically bonded together. They are not considered individual atoms because they contain multiple atoms connected by chemical bonds.
Ions are electrically charged particles formed when atoms gain or lose electrons. They can be positively charged (cations) or negatively charged (anions).
Subatomic particles are the constituents of atoms. They include protons, neutrons, and electrons.
Compounds are substances composed of two or more different elements chemically combined.

What can the students expect to be true about the two masses?
The mass of the ice cubes will be greater because solids are more dense.
The mass of the ice cubes will be greater because they took up more space in the beaker.
The mass of the ice cubes and the water will be equal because the same amount of matter is in the beaker
The mass of the ice cubes and the water will be equal because their particles have the same amount of energy

The mass of the ice cubes and the water will be equal because the same amount of matter is in the beaker.
Matter is anything that has mass and occupy space. All substances are composed of matter. According to the law of conservation of mass, matter can neither be created nor destroyed but can be converted from one form to another.
Since mass is the quantity of matter in a substance, the mass of the ice cubes and the water will be equal because the same amount of matter is in the beaker.

What did the periodic table help scientists discover?
Scientists can use the table to analyze reactivity among elements, predict chemical reactions, understand trends in periodic properties among different elements and speculate on the properties of those yet to be discovered.
What type of bond if formed between the atoms of this type of compound
Answer:
The main component are electrons.
A chemical bond is any attractive interaction that keeps atoms short. This interaction can be directional as the bond between two atoms within a molecule, or non-directional as the electrostatic interaction that keeps the ions of an ion crystal in contact. It can be strong like the two previous examples, or weak as van der Waals interactions that are dipolar in nature.
Many models exist to describe these interactions. For example, the chemical bond between two atoms within a molecule can be described with the Lewis model or with a quantum model, like the theory of molecular orbitals. In both cases, the origin of the interaction is a sharing of electrons between the two partner atoms of the chemical bond.
There are three types of chemical bonds: single bonds, double bonds, and triple bonds. Indeed, the type of chemical bond depends on the number of electrons shared between the bound atoms:
* Simple bonds have 2 shared electrons.
* Double bonds have 4 shared electrons.
* Triple bonds have 6 shared electrons.
This number of electrons shared between the atoms depends on the electronic structure of these atoms and thus on the rules of the byte and the duet.
