Gas Laws and Kinetic Theory of Gases

Gas laws involve what three variables?

• Solid Liquid Gas 
• Speed Velocity Acceleration 
• Elements Compounds Mixtures 
• Pressure Temperature Volume 

For a gas, which pair of variables are inversely proportional to each other (if all other conditions remain constant)?

• P, T

• P, V

• V, T

• n, P

• I only

• I and II only

• II and III only

• I, II and III

According to the Combined Gas Law, pressure and volume are inversely related which means that

• When pressure increases, volume increases
• When pressure decreases, volume decreases
• When pressure increases, volume decreases
• When pressure doubles, volume triples

If you increase the pressure, what will happen to the temperature, if volume is constant?

• Increase
• Decrease
• Stay the same
• It will Blow Up

What is 50 C in Kelvin?

• 223
• 323
• 100
• 50

The temperature at which all molecular motion stops is

• -460 ^.C
• -273K
• 0K
• 0^.C

The kinetic theory of matter states that all of the particles that make up matter are constantly

• growing
• shrinking
• crying
• moving
