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 400 mL at 120°C, what is the new volume at 200°C if pressure is constant?

Back

Using Charles's Law, the new volume can be calculated as V2 = V1 * (T2/T1). V2 = 400 mL * (200 + 273.15)/(120 + 273.15) = 687.75 mL.

Front

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

Back

The relationship is inverse; as one increases, the other decreases, provided the temperature remains constant.

Front

What is the formula for calculating pressure using Boyle's Law?

Back

The formula is P1V1 = P2V2, where P is pressure and V is volume.

Front

If the pressure of a gas is 740 torr and its volume is 250 mL, what will be the volume at 800 torr?

Back

Using Boyle's Law, V2 = V1 * (P1/P2). V2 = 250 mL * (740/800) = 231 mL.

Front

What is the effect of cooling a gas at constant pressure?

Back

Cooling a gas at constant pressure will decrease its volume, according to Charles's Law.
