Gas Laws Conceptual

Front

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

Back

Inverse relationship: As the volume of a gas increases, the pressure decreases, and vice versa.

Front

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

Back

The pressure decreases.

Front

What is the final pressure of a gas if it is cooled from 323.0 K to 273.15 K at constant volume, starting from 750.0 mmHg?

Back

634 mmHg.

Front

True or False: Gases can be compressed.

Back

True.

Front

What is the number of moles in a 99.2 L container of gas at STP?

Back

4.43 moles.

Front

What is Boyle's Law?

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume at constant temperature.

Front

What is Charles's Law?

Back

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

Front

Define STP in terms of gas laws.

Back

STP stands for Standard Temperature and Pressure, which is 0 degrees Celsius (273.15 K) and 1 atm pressure.

Front

What is the ideal gas law equation?

Back

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

Front

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

Back

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