Question

HELP ASAP 50 POINTS EACH!!!!!!!!!! Based on the kinetic molecular theory, which of the following statements is correct about a sample of gas at a constant temperature and volume?

The net kinetic energy of its particles decreases due to collisions.

The net kinetic energy of its particles increases due to collisions.

lt has a constant average kinetic energy.

Its average kinetic energy is always zero.

Answer 1

C, it has a constant average kinetic energy is the correct statement.

Explanation: The kinetic molecular theory of gases states that a gas contains an enormous number of atoms/molecules.

The kinetic-molecular theory of gases can be stated as such: A gas consists of molecules in constant random motion. Gas molecules influence each other only by collision; they exert no other forces on each other. All collisions between gas molecules are perfectly elastic; all kinetic energy is conserved.

Happy to help, have a great day! :)

Answer 2

It has a constant average kinetic energy.

Step-by-step explanation:

According to the kinetic molecular theory, the particles of a gas are in constant random motion and possess kinetic energy. This kinetic energy is directly proportional to the temperature of the gas.

If the sample of gas is at a constant temperature and volume, it means that the average kinetic energy of its particles is constant.
