Ideal and Combined Gas Laws

If I have 5.6 liters of gas in a piston at a pressure of 1.5 atm and compress the gas until its volume is 4.8 L, what will the new pressure inside the piston be?

• 1.8 atm

• 3.27 atm

• 1.8 L

• 3.27 atm

Under what conditions is a real gas like an ideal gas?

• High temperature, high pressure

• Low temperature, high pressure

• High temperature, low pressure

• Low temperature, high pressure

If I initially have 4.0 L of a gas at a pressure of 1.1 atm, what will the volume be if I increase the pressure to 3.4 atm?

• 1.29 L

• 12.36 L

• 1.29 atm

• 12.36 atm

Hydrogen gas was cooled from 150^oC to 50^oC. Its new volume is 75 mL. What was its original volume?

• 98 mL

• 98 K

• 98^oC

• 98 L

Gas inside a balloon originally had a volume of 3.12 L. Ernesto decides to sit on the balloon and compresses it to a final volume of 0.12 L and a final pressure of 3.14 atm. What was the original pressure?

• 2.29 atm

• 0.12 atm

• 8.28 atm

Gas laws involve what three variables?

• Solid Liquid Gas 

• Speed Velocity Acceleration 

• Elements Compounds Mixtures 

• Pressure Temperature Volume 

What is the relationship between volume and pressure?

• flipped

• direct

• inverse

• none

what relationship does this graph show?

• temperature and pressure- direct

• temperature and pressure- inverse

• pressure and volume- direct

• pressure and volume- inverse

As pressure increases, temperature increases. Describe the relationship:

• Direct Relationship

• Inverse Relationship

• No Relationship

• This is an example of Charles's law
• This is an example of Boyle's law
