1/13 DLD- Behavior of Gases

10 mL of gas is placed into a tube, sealed and left sitting on the table in the room.

Because the ​ (a)   is held constant, in order to increase the ​pressure in the tube, the ​ (b)   must be increased.

• temperature
• pressure

Summarize the relationship between temperature and pressure of a gas:

When ​ (a)   is held constant, if temperature is increased, pressure will ​ (b)

A sample of a gas has a volume of 852 mL at 298 K. If the pressure is held constant and the temperature is increased to 400 K, what will happen to the volume?

• It will increase

• It will decrease

• It will remain constant

If you decrease the volume of a gas at a constant temperature, will the pressure of the gas increase, decrease or remain constant?

• It will increase

• It will decrease

• It will remain constant

The images below show three sealed containers of gas in a water bath on a hot plate. Each container is at a different temperature.

Put the containers in order of increasing pressure

(1= most pressure, 3= least pressure)

You’re holding an inflated balloon in your hand. Because the balloon is in the same environment and the change happens quickly, we consider the ​ (a)   to remain constant. When you squeeze the balloon, the ​ (b)   on the balloon will ​ (c)   and as a result, the ​ (d)   of the balloon will ​ (e)

The image shows a container of air at a constant temperature. The pressure is changed from P1 to P2. Explain how the change from P1 to P2 affects the volume and density of the gas:

From P1 to P2, the pressure ​ (a)   . This change in pressure causes the volume to ​ (b)   which causes the density to ​ (c)

• decrease
• remain constant

A balloon is filled with 10 L of air at a pressure of 5 atm. Explain what would happen to the pressure of the balloon if the volume is changed to 20 L while the temperature stays constant.
