Gas Laws Test Review

Front

What causes gas pressure?

Back

Gas pressure is caused by gas molecules colliding with the walls of the container.

Front

What is the First Law of Thermodynamics?

Back

The First Law of Thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What happens to pressure if the temperature of a gas changes while volume and number of particles remain constant?

Back

If the temperature of a gas changes while volume and number of particles remain constant, the pressure must also change.

Front

What does the Kinetic Molecular Theory state about gas particles?

Back

The Kinetic Molecular Theory states that gas particles are elastic, do not attract each other, and that energy is not lost when they collide.

Front

True or False: Gases can be compressed.

Back

True

Front

What is the relationship between temperature and kinetic energy in gases?

Back

The kinetic energy of gas particles is directly dependent on temperature; as temperature increases, kinetic energy increases.

Front

Define Boyle's Law.

Back

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

Front

Define Charles's Law.

Back

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

Front

What is the ideal gas law equation?

Back

The ideal gas law is represented by the equation 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.

Front

What is the significance of the absolute zero temperature?

Back

Absolute zero is the theoretical temperature at which a gas would have zero kinetic energy, and it is 0 Kelvin or -273.15°C.
