What happens to the average kinetic energy of a gas when the particles of the gas collide against each other at a constant temperature and volume? The average kinetic energy remains constant. The average kinetic energy drastically increases. The average kinetic energy drastically decreases. The average kinetic energy gets added to the potential energy.

The average kinetic energy drastically increases.

Explanation:

The average kinetic energy drastically increases when the gas particles collide against each other at a constant temperature and volume because the collision will increase the heat content of gas at a particular temperature and gas particles begin to move faster as gain more kinetic energy.

Hence, the correct answer is "B".

the average kinetic energy remains constant

Explanation:

Collisions between gas particles are elastic. An elastic collision means there is no net gain or loss of kinetic energy due to the collision. This means a sample of gas will have a constant average kinetic energy at a constant temperature and volume.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

the objects have the same charge is correct.
