Classwork 12/13: Combined Gas Law

Front

What is the Combined Gas Law?

Back

The Combined Gas Law relates the pressure, volume, and temperature of a gas. It is expressed as (P1V1)/T1 = (P2V2)/T2.

Front

What is the formula to convert Celsius to Kelvin?

Back

To convert Celsius to Kelvin, add 273 to the Celsius temperature.

Front

What happens to the volume of a gas when the temperature decreases?

Back

The volume of a gas decreases when the temperature decreases, assuming pressure is constant.

Front

What is the relationship between pressure and volume in a gas?

Back

According to Boyle's Law, pressure and volume are inversely related; as volume decreases, pressure increases.

Front

What is the standard atmospheric pressure in atm?

Back

Standard atmospheric pressure is 1 atm.

Front

How do gas molecules behave in a container?

Back

Gas molecules move constantly and randomly, colliding with each other and the walls of the container.

Front

What happens to the pressure of a gas if its volume is halved?

Back

If the volume of a gas is halved, the pressure will double, assuming temperature is constant.

Front

What is the effect of increasing temperature on gas pressure?

Back

Increasing the temperature of a gas increases its pressure if the volume is held constant.

Front

What is the Kelvin temperature of absolute zero?

Back

Absolute zero is 0 Kelvin.

Front

If a gas has a pressure of 2 atm and a volume of 3 L, what is the product of pressure and volume?

Back

The product of pressure and volume is 6 atm·L.
