Gas Laws and Volume Calculations

Front

What is 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. (P1V1 = P2V2)

Front

What is Charles' Law?

Back

Charles' Law states that the volume of a gas is directly proportional to its temperature in Kelvin when pressure is held constant. (V1/T1 = V2/T2)

Front

What is Gay-Lussac's Law?

Back

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

Front

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

Back

The volume is halved, according to Boyle's Law.

Front

What is the formula to calculate the new volume of a gas when pressure changes?

Back

V2 = (P1V1)/P2, where P1 and V1 are the initial pressure and volume, and P2 is the new pressure.

Front

How do you convert pressure from torr to atm?

Back

To convert torr to atm, divide the pressure in torr by 760. (Pressure in atm = Pressure in torr / 760)

Front

What happens to the volume of a gas if the temperature increases while pressure is constant?

Back

The volume increases, according to Charles' Law.

Front

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

Back

Pressure increases as temperature increases, according to Gay-Lussac's Law.

Front

Calculate the new pressure if the volume of a gas decreases from 5 L to 2 L while temperature is constant and initial pressure is 1 atm.

Back

The new pressure is 2.5 atm, using Boyle's Law (P1V1 = P2V2).

Front

What is the significance of absolute zero in gas laws?

Back

Absolute zero (0 K) is the theoretical temperature at which gas particles have minimum energy and volume.
