Gases Kmt

According to the kinetic molecular theory, the pressure of a gas

• will decrease as the temperature increases

• would increase if the mass of the gas particles would be greater

• results from collisions of the gas particles with the container walls

• none of the above are true

According to the kinetic-molecular theory, gas particles

• are spaced far apart

• are constantly moving

• have rapid random motion

• all of the above

• 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
