Final Exam-Gas Laws

Front

What happens to gas pressure when temperature increases?

Back

Gas pressure increases with an increase in temperature, assuming volume is constant.

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.

Front

If the volume of a gas is halved, what happens to its pressure?

Back

The pressure doubles, according to Boyle's Law.

Front

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

Back

Pressure and volume are inversely related; as one increases, the other decreases.

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 absolute temperature.

Front

If the temperature of a gas is tripled, what happens to its volume?

Back

The volume also triples, assuming pressure is constant.

Front

What is the ideal gas law equation?

Back

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

Front

What happens to gas pressure if the volume is decreased?

Back

Gas pressure increases when the volume is decreased, assuming temperature is constant.

Front

What is the effect of adding more gas to a container at constant volume?

Back

Adding more gas increases the pressure in the container.

Front

What is absolute zero?

Back

Absolute zero is the theoretical temperature at which a gas has zero volume and pressure, equivalent to -273.15°C or 0 K.
