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.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

the answer is d. 74.02
