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 happens to the volume of a gas when the pressure increases at constant temperature?

Back

The volume of the gas decreases.

Front

How do you convert Celsius to Kelvin?

Back

To convert Celsius to Kelvin, add 273.15 to the Celsius temperature.

Front

What is the effect of increasing temperature on the pressure of a gas at constant volume?

Back

Increasing the temperature of a gas at constant volume increases its pressure.

Front

If the volume of a gas is halved, what happens to its pressure at constant temperature?

Back

The pressure of the gas doubles.

Front

What is the relationship between temperature and volume of a gas at constant pressure?

Back

At constant pressure, the volume of a gas increases as the temperature increases.

Front

What is the standard atmospheric pressure in atm?

Back

Standard atmospheric pressure is 1.00 atm.

Front

If a gas occupies 10.0 L at 2.0 atm, what will be its volume at 1.0 atm if the temperature remains constant?

Back

The volume will increase to 20.0 L.

Front

What happens to the volume of a gas when it is cooled?

Back

The volume of the gas decreases.

Front

What is the formula to calculate pressure using the Combined Gas Law?

Back

P = (P1V1T2)/(V2T1) where P is pressure.
