Kinetic Molecular theory

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

• 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

According to the Kinetic Molecular Theory a liquid's (SELECT ALL THAT APPLY)

• particles are held close together by intermolecular forces

• particles are in constant motion

• particles are vibrating in place and closely packed

• particles are not moving

The kinetic energy of a gas particle is proportional to its

• temperature in Celsius

• volume

• temperature in Fahrenheit.

A gas A has three times the molar mass of gas B, then_______________.

•   gas B diffuses slower than A

• gas A and B diffuses at the same rate

• gas B diffuses faster than gas A.

• a mole of gas A is lighter than a mole of gas B
