Susan Kline · Answer 1

When a sample of a gas is contained in a closed rigid cylinder and the gas inside the cylinder is heated " (3) The average velocity of the gas molecules increases". The number of molecules stays the same.

Tamia Dougherty · Answer 2

The answer is (3) The average velocity of the gas molecules increases. In the closed rigid cylinder, the volume of the gas and number of gas molecules will not change. The number of collision will increase.
