Gas Laws

Front

What is the formula to convert Celsius to Kelvin?

Back

K = °C + 273.15

Front

What is the definition of atmospheric pressure?

Back

The force exerted by the weight of air above a surface.

Front

What is a Barometer used for?

Back

A device that measures atmospheric pressure.

Front

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

Back

The volume decreases.

Front

What is Charles's Law?

Back

At constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin.

Front

What is Boyle's Law?

Back

At constant temperature, the volume of a gas is inversely proportional to its pressure.

Front

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

Back

As pressure increases, volume decreases (Boyle's Law).

Front

What happens to the volume of a gas if the temperature is increased at constant pressure?

Back

The volume increases.

Front

What is the ideal gas law equation?

Back

PV = nRT, where P = pressure, V = volume, n = number of moles, R = ideal gas constant, T = temperature in Kelvin.

Front

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

Back

The volume of the gas decreases.
