What does the Pressure Law (Gay-Lussac’s Law) state?

Back

For a fixed mass of gas at constant volume, pressure (P) is directly proportional to absolute temperature (T) in Kelvin.

Front

What is the relationship described by the Pressure Law?

Back

P/T = constant.

Front

What happens to gas pressure when the temperature in a sealed container is increased?

Back

Gas pressure increases linearly; doubling the Kelvin temperature doubles the pressure.

Front

What does Charles’s Law state?

Back

At constant pressure, volume (V) is proportional to temperature (T).

Front

What is the relationship described by Charles’s Law?

Back

V/T = constant.

Front

What happens to gas volume when the absolute temperature increases at constant pressure?

Back

A rise in absolute temperature yields a proportional increase in gas volume.

Front

How do hot air balloons rise according to Charles’s Law?

Back

The heated air inside expands, increasing the volume and allowing the balloon to rise.

Front

What is the Combined Gas Law?

Back

P1V1/T1 = P2V2/T2, integrating pressure, volume, and temperature for situations where they change simultaneously.

Front

What do these gas laws provide for real gases?

Back

A valuable first approximation under many practical conditions.
