Properties of Gasses

Front

What is the definition of gas pressure?

Back

Gas pressure is the force exerted by gas particles colliding with the walls of a container, measured in units such as atm or pascals.

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 (P1V1 = P2V2).

Front

What happens to the volume of a gas when the temperature decreases?

Back

According to Charles's Law, the volume of a gas decreases as the temperature decreases, assuming pressure is constant.

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) at constant pressure (V1/T1 = V2/T2).

Front

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

Back

According to Gay-Lussac's Law, the pressure of a gas is directly proportional to its temperature (in Kelvin) at constant volume (P1/T1 = P2/T2).

Front

What happens to gas pressure when the volume decreases?

Back

When the volume of a gas decreases, the pressure increases, assuming temperature remains constant (Boyle's Law).

Front

What is the ideal gas law?

Back

The ideal gas law is an equation of state for an ideal gas, represented as 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 is the effect of increasing the pressure on the temperature of a gas?

Back

Increasing the pressure of a gas at constant volume will increase its temperature, according to Gay-Lussac's Law.

Front

What is the definition of absolute zero?

Back

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

Front

What is the significance of the gas constant (R) in the ideal gas law?

Back

The gas constant (R) is a proportionality constant that relates the pressure, volume, temperature, and amount of gas in the ideal gas law.
