Review of Gas Laws

Gas laws involve what three variables?

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

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

According to the Combined Gas Law, volume and temperature are directly related. This means that

• When volume increases, temperature increases
• When volume increases, temperature decreases
• When volume double, pressure triples
• When volume doubles, volume is reduced by 1/2

If 6L of gas at 293K is compressed to 4L, what is the new temperature? 

• 195K
• 439.5K
• 0.082K
• 12.2K

4L of a gas is contained at 300 kPa and 200K. What will its volume be in L at 140 kPa and 100K?

• 4.3L
• 4.8L
• 6.2L
• 8.5L

If a balloon is cooled what will happen to the volume?

• Volume will increase
• Volume will decrease
• Volume will not change

• 204 K
• 200 K
• 2046 K
• 2000 K

Consider a sample of oxygen gas at 27° C with a volume of 9.55L at a pressure if 2.97 atm.  The pressure is changed to 8.25 atm and the gas is heated to 125° C.  What’s the new volume? 

• 4.56 L
• 4.6 L
• 15.9 L
• 16 L
