Gas Laws and Kinetic Molecular Theory

Gas pressure is caused by

• gas molecules colliding with surfaces

• gas molecules hitting other gas molecule

• gas molecules condensing to a liquid

• barometers

Which of the following is true about KMT?

• Gas particles are elastic and do not attract each other.

• Energy is not lost when gas particles collide with each other or with the walls of the container.

• The kinetic energy of gas is dependent on temperature

• All of the above.

What about gasses can be measured?

• Pressure, number of molecules and Volume

• Temperature, Density Volume, and Pressure

• Volume, Density and Temperature

• Pressure, Temperature, Volume, and Number of molecules

If you increase the pressure of a constant volume of gas, what will happen to the temperature?

• Increase

• Decrease

• Stay the same

• It will Blow Up

What is the basis of kinetic-molecular theory?

• Molecules are in constant motion.
• Molecules only stop sometimes.
• Approximately half the molecules are stationary.
• It is impossible to tell if a molecule is moving or not.
