Answer:Temperature affects storage time and food deteriorates faster at higher temperatures. Microorganisms grow rapidly at room temperature . Thus to slow microbial growth, enzymatic and oxidative processes, food must be stored at room temperature.
Due to decomposition reactions with oxygen or carbon dioxide in the air, meat begins to feel slimy and smell spoiled. ... Because of its smaller surface area, the unsliced meat would have less collisions and therefore, a slower reaction rate.
Explanation:
A gas at 1.5 atm had pits ressure decreased to 0.50 atm producing a new volume of 750 ml what was its original volume
Answer:
The original volume of the gas is 0.001 mL
Explanation:
This easy excersise can be solved by the law for gases, about pressure and volume; the volume of a gas is inversely proportional to the pressure it exerts.
We can propose the rule by this formula:
P₁ / V₁ = P₂ / V₂
We replace data given: 1.50 atm / V₁ = 0.50 atm / 750 mL
As the rule says, that volume is inversely proportional, and the pressure was decreased, volume must be lower than 750 mL.
1.5atm / (0.5 atm / 750mL) = V₁
V₁ = 0.001 mL

Most gases exist as molecules, for example, fluorine is F2.
Explain why the elements in Group 0 exist as single atoms.
Group 0 is the noble gas elements in periodic table. They are all unreactive because, they have completely filled electronic configuration and thus they are stable. This stability to be a single element make them so.
What are noble gases?Noble gases are helium, neon, argon, krypton and xenon. They are 18th group elements in periodic table. Also called zero group elements. The general electronic configuration of these elements is ns² np⁶.
Noble gases contains eight electrons in their valence shell and thus completed octet. Atoms with less number of electrons in valence shell tends to attain octet by losing or gaining electrons to their valence shell.
Every elements except noble gases are electron deficient or electron rich. The electron rich elements will lose their electron to attain stability and the elements with less electrons gain them through bonding. That's why they are existing as molecules.
Therefore, the elements of zero group are highly stable and they do not lose or gain electrons to form molecules.

A soccer player applies a force of 56.6 N to a soccer ball while kicking it. If the ball has a mass of 0.46 kg, what is the acceleration of the soccer ball?
Answer:
[tex]a=123.04\ m/s^2[/tex]
Explanation:
Given that,
Force applied to a soccer player, F = 56.6 N
The mass of the ball, m = 0.46 kg
We need to find the acceleration of the soccer ball. The force acting on the ball is given by :
F = ma
Where
a is the acceleration
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{56.6 }{0.46 }\\\\a=123.04\ m/s^2[/tex]
So, the required solution is [tex]123.04\ m/s^2[/tex].

A sample of neon gas occupies a volume of 752 mL at 25 degrees Celsius. What volume will the gas occupy at -10 degrees Celsius?
Answer:
New volume v2 = 300.8 ml
Explanation:
Given:
Old volume v1 = 752 ml
Old temperature T1 = 25°C
New temperature T2 = -10°C
Find:
New volume v2
Computation:
Using Ideal gas law formula
V1T2 = V2T1
(752)(-10) = (V2)(25)
New volume v2 = 300.8 ml

What is electrical energy? Give an example.
Answer:
Specific examples of electrical energy include:
Alternating current (AC)
Direct current (DC)
Lightning
Batteries
Capacitors
Energy generated by electric eels
Explanation:
Electrical energy used for electric power, such as wall current used to power a light bulb or computer, is energy that is converted from electric potential energy. This potential energy is converted into another type of energy (heat, light, mechanical energy, etc). For a power utility, the motion of electrons in a wire produces the current and electric potential.
A battery is another source of electrical energy, except the electrical charges may be ions in a solution rather than electrons in a metal.
Biological systems also use electrical energy. For example, hydrogen ions, electrons, or metal ions may be more concentrated on one side of a membrane than the other, setting up an electrical potential that can be used to transmit nerve impulses, move muscles, and transport materials.
Energy does not change form. True or False
Answer:
Energy can change form, so False
Answer: False
Explanation:Energy readily changes from one form to another. The law of Conservation of Energy states that "Energy cannot be created or destroyed.". In other words, the total amount of energy in the universe never changes, although it may change from one form to another. Energy never disappears, but it does change form.
