Q

The average molecular kinetic energy of a gas can be determined by knowing only

a) the volume of the gas

b) the number of molecules in the gas

c) the temperature of the gas

d) the pressure of the gas

A

Answer: C. The temperature of the gas.

Explanation: The average molecular kinetic energy of a gas is directly proportional to the temperature of the medium containing the gas. As the temperature of the gas increases, the molecules of the gas vibrate faster, causing an increase in the average kinetic energy. The reverse is what happens when the temperature is reduced.
