Boyles and Charles Gas Law Flashcard

Front

What is Boyle's Law?

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume when the temperature is held constant. Mathematically, 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 the pressure is held constant. Mathematically, V1/T1 = V2/T2.

Front

How do you convert Celsius to Kelvin?

Back

To convert Celsius to Kelvin, add 273.15 to the Celsius temperature. K = °C + 273.15.

Front

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

Back

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

Front

What happens to the pressure of a gas when its volume decreases at constant temperature?

Back

According to Boyle's Law, the pressure of a gas increases when its volume decreases at constant temperature.

Front

If a gas has a volume of 200 mL at 600 K, what will its volume be at 300 K if pressure is constant?

Back

100 mL (using Charles's Law: V1/T1 = V2/T2).

Front

What is the relationship between pressure and volume in Boyle's Law?

Back

The relationship is inverse; as one increases, the other decreases.

Front

What is the formula for Boyle's Law?

Back

P1V1 = P2V2.

Front

What is the formula for Charles's Law?

Back

V1/T1 = V2/T2.

Front

What is the effect of temperature on gas volume at constant pressure?

Back

Increasing temperature increases gas volume; decreasing temperature decreases gas volume.
