Gas Law Test Review

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's Law?

Back

Charles's 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 the Ideal Gas Law?

Back

The Ideal Gas Law relates pressure, volume, temperature, and the number of moles of a gas: PV = nRT.

Front

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

Back

As the volume of a gas decreases, its pressure increases, provided the temperature remains constant.

Front

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

Back

As the temperature of a gas increases, its volume increases, provided the pressure remains constant.

Front

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

Back

As the temperature of a gas increases, its pressure increases, provided the volume remains constant.

Front

How do you convert mmHg to atm?

Back

To convert mmHg to atm, divide the pressure in mmHg by 760. (1 atm = 760 mmHg)

Front

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

Back

Using Boyle's Law: V2 = (P1 * V1) / P2.

Front

What is the formula to calculate the final temperature of a gas when volume changes?

Back

Using Charles's Law: T2 = (V2 * T1) / V1.

Front

What is the significance of the Kelvin scale in gas laws?

Back

The Kelvin scale is used in gas laws because it is an absolute temperature scale, where 0 K represents absolute zero.
