• The pressure will increase

• The pressure will not change

• The pressure will descrease

10mL of water is placed in aluminum can and put on a hot plate. When the water inside the can begins to boil, the can is turned upside-down and placed into a bowl of cold water. This causes the can to crush instantly. The picture to the left shows the result.

Which explanation is best at describing why the can was crushed?

• A chemical reaction occurred between the hot water in the can and the cold water in the bowl.

• The cold water caused the air pressure inside the can to quickly drop below the air pressure outside the can.

• The air inside the can escaped the can when it was turned upside down.

• The bowl of water has a larger volume than the soda can causing the volume of the can to go down.

A closed container full of nitrogen gas has a pressure of 2atm. What can a person do to the gas to increase the pressure to 3atm?

• Increase the temperature of the gas.

• Decrease the temperature of the gas.

• The container is closed, so there is no way to increase the pressure.

• There is not enough information given.

What type of variation relationship exists between temperature and pressure?

• Direct Variation

• Inverse Variation

• Quadratic Variation

• Exponential Variation

A student measures the pressure and volume of an empty water bottle to be 1.4 atm and 2.3 L. She then decreases the pressure to 0.65 atm. What is the new volume?

• 2.1 L

• 5.0 L

• 8.2 L

1. On a cold winter day, Serena buys some helium-filled balloons from a supermarket for a friend's birthday party. The supermarket is heated, and the temperature is warm inside. After taking them outside, they seem to have deflated. Yet, when the balloons are in a heated car, they return to their original size.     

Explain what is happening with the balloons in terms of temperature, particle movement, and volume.
