Gas Laws

Front

What is absolute zero?

Back

Absolute zero is 0 K, the temperature where particles have no kinetic energy, and the coldest temperature possible.

Front

Which of the following is NOT a value for standard pressure?

Back

1 torr is NOT a value for standard pressure.

Front

What happens to the pressure of a gas if the temperature increases?

Back

If the temperature of a gas increases, the pressure increases.

Front

What happens to the volume of a balloon when it is cooled?

Back

The volume of the balloon will decrease when it is cooled.

Front

What type of relationship does a direct graph show?

Back

A direct graph shows a direct relationship between two variables.

Front

Define 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

What is the ideal gas law equation?

Back

The ideal gas law is represented by the equation PV = nRT.

Front

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

Back

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

Front

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

Back

Pressure and volume have an inverse relationship; as one increases, the other decreases.
