1. Mixed up Gas Law Review

2. Explain why an unopened bag of potato chips left in a hot car appears to become larger.

3. The air inside a bicycle pump is compressed from 2L to 1L and the temperature remains constant. Will the pressure increase, decrease, or stay the same? Explain.

4. An inflated balloon is placed in your car on a cold winter day
An inflated balloon is placed in your car on a cold winter day. Will the volume of the balloon increase, decrease, or stay the same? Explain.

5. State the following relationships and tell if they are directly or inversely proportional.
a) As pressure increases volume ____________ meaning they are ___________proportional.
b) As temperature decreases pressure _____________meaning they are _____________ proportional.
c) As volume increases temperature ________________meaning they are ____________ proportional
d) As pressure increases the number of molecules (n) _______________ meaning they are _____________ proportional.

6. Assuming pressure remains constant, what is the volume of the gas in a balloon at -195°C if the balloon has been filled to a volume of 5.0 L at 25°C?

7. The pressure of a sample of helium in a 1.00-L container is atm. What is the new pressure if the sample is placed in a 2.00-L container?

8. If a gas sample has a pressure of 0. 30 atm at 0
If a gas sample has a pressure of 0.30 atm at 0.00°C, by how much does the temperature have to decrease to lower the pressure to 0.28 atm? Assume constant volume.

9. The pressure of a sample of helium in a 1. 00 L container is 0. 988atm
The pressure of a sample of helium in a 1.00 L container is 0.988atm. What is the new pressure if the sample is placed in a 2.00 L container?
