Boyles, Charles & Combined Gas Laws 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. Formula: P1V1 = P2V2.

What is the formula for Boyle's Law?

Back

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.

Front

What is the formula for Charles's Law?

Back

V1/T1 = V2/T2.

Front

What is the Combined Gas Law?

Back

The Combined Gas Law combines Boyle's and Charles's Laws: (P1V1)/T1 = (P2V2)/T2.

How do you convert Celsius to Kelvin?

Back

To convert Celsius to Kelvin, add 273.15 to the Celsius temperature.

Front

What is 50°C in Kelvin?

Back

323 K.

Front

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

Back

According to Boyle's Law, if the pressure decreases, the volume increases, assuming temperature remains constant.

Front

What happens to the volume of a gas when its temperature increases?

Back

According to Charles's Law, the volume of a gas increases as its temperature increases, assuming pressure remains constant.

Front

What is the new volume of a gas if the pressure on 350 L of oxygen at 720 mm Hg is decreased to 600 mm Hg?

Back

420 L.
