Kinetic Molecular Theory of Gases

Gas pressure is caused by

• gas molecules colliding with surfaces
• gas molecules condensing to a liquid
• gas molecules hitting other gas molecule
• barometers

• Flask 1 contain the most molecules
• Flask 2 contain the most molecules
• Flask 3 contain the most molecules
• Flask 4 contain the most molecules

• Flask 1 contain the least pressure
• Flask 2 contain the least pressure
• Flask 3 contain the least pressure
• Flask 4 contain the least pressure

• Since all flask have same amount of gas, flask 1 has the least pressure
• Since all flask have same amount of gas, flask 2 has the least pressure
• Since all flask have same amount of gas, flask 3 has the least pressure
• Since all flask have same amount of gas, flask 4 has the least pressure

• Gases do not move in straight line
• 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
