11.5 Gases Quiz

At a constant temperature, the volume decreases.  What happens to the pressure?

• increases

• decreases

• stays the same

In gases, pressure is

• directly proportional to volume

• inversely proportional to volume

• directly proportional to friction

• inversely proportional to heat

The temperature of gas is held constant, while its volume is decreased. The pressure exerted by the gas on the wall of the container increases, because its molecules

• Strike the walls with large farce

• Strike the walls more frequently

• Are in contact with the walls for a shorter time

• Viscosity

• Barometer

• Pressure
