Kinetic Molecular Theory

Which one of the following is not a statement of kinetic theory of gases?

• The KE depends upon the temperature of the gas

• The KE depends upon the pressure of gas

• The collisions are elastic

• Pressure of gas is due to collisions of gas molecules on the walls of the container

Gas molecules exert pressure on the walls of the container because of

• momentum

• they obey gas laws

• they collide with each other

• they have finite volume

Pressure is caused by

• gravity

• gas molecules colliding with each other

• gas molecules colliding with surface

• gas molecules reacting with each other

At higher temperatures

• particles in an object have less energy

• particles in an object move faster

• a gas contracts

• Most of the volume of gas is empty space
• Gas particles are not in constant random motion
• Gas particles attract each other

• Gas particles are elastic and do not attract each other.
• The kinetic energy of gas is dependent on temperature 
• Energy is not lost when gas particles collide with each other or with the walls of the container.
• All of the above
