Combined Gas Laws

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.

What is Boyle's Law?

Back

Boyle's Law states that the pressure and volume of a gas have an inverse relationship when temperature is held constant. As pressure increases, volume decreases.

Front

What is Charles's Law?

Back

Charles's Law states that the volume of a gas is directly proportional to its temperature (in Kelvin) when pressure is held constant.

Front

What is the relationship between pressure and temperature in Gay-Lussac's Law?

Back

Gay-Lussac's Law states that the pressure of a gas is directly proportional to its temperature (in Kelvin) when volume is held constant.

Front

How do you convert Celsius to Kelvin?

Back

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

Front

If the pressure of a gas is tripled, what happens to its volume according to Boyle's Law?

Back

The volume will be 1/3 of its original volume.

Front

What is the formula for calculating the pressure of a gas mixture?

Back

The total pressure of a gas mixture is the sum of the partial pressures of each gas: P_total = P1 + P2 + P3 + ...

Front

What is the ideal gas equation?

Back

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

Front

What happens to the volume of a gas if its temperature increases while pressure remains constant?

Back

The volume of the gas increases according to Charles's Law.

Front

What is the significance of absolute zero in gas laws?

Back

Absolute zero (0 K) is the theoretical temperature at which a gas would have zero volume and pressure.
