Gas Laws

Front

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

Back

The volume increases.

Front

What is the relationship between pressure and volume of a gas according to Boyle's Law?

Back

The relationship is inverse; as pressure increases, volume decreases.

Front

What is the formula for Charles's Law?

Back

V1/T1 = V2/T2, where V is volume and T is temperature in Kelvin.

Front

What is the formula for Boyle's Law?

Back

P1V1 = P2V2, where P is pressure and V is volume.

Front

What happens to gas pressure when the temperature increases?

Back

The pressure increases if the volume is constant.

Front

What is the effect of decreasing the volume of a gas on its pressure?

Back

The pressure increases, assuming temperature remains constant.

Front

What is the ideal gas law formula?

Back

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

Front

What is the gas constant (R) value in the ideal gas law?

Back

R = 0.0821 L·atm/(K·mol) or 8.314 J/(K·mol).

Front

How do you convert Celsius to Kelvin?

Back

K = °C + 273.15.

Front

What happens to the pressure of a gas if more gas is pumped into a fixed volume?

Back

The pressure increases.
