Gas Laws

Front

What is Boyle's Law?

Back

Boyle's Law states that at constant temperature, the pressure of a gas is inversely proportional to its volume. The formula is P1V1 = P2V2.

Front

What happens to the volume of a gas when pressure increases?

Back

The volume of a gas decreases when pressure increases, assuming temperature remains constant.

Front

What happens to the temperature of a gas when its pressure doubles at constant volume?

Back

The temperature of the gas also doubles.

Front

What two variables are compared in Gay-Lussac’s Law?

Back

Gay-Lussac’s Law compares temperature and pressure.

Front

To what temperature scale must all temperature measurements be converted for gas law calculations?

Back

All temperature measurements must be converted to Kelvin.

Front

What is Charles's Law?

Back

Charles's Law states that at constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin.

Front

What is the formula for Charles's Law?

Back

The formula for Charles's Law is V1/T1 = V2/T2.

Front

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

Back

The volume of the gas increases when its temperature increases.

Front

What is the ideal gas law?

Back

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

Front

What does the 'R' in the ideal gas law represent?

Back

'R' is the ideal gas constant, which is 0.0821 L·atm/(K·mol) or 8.314 J/(K·mol) depending on the units used.
