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 calculate the new pressure of a gas when its volume decreases?

Back

Use Boyle's Law: P1V1 = P2V2. Rearrange to find P2: P2 = P1V1/V2.

Front

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

Back

According to Charles's Law, the volume increases as the temperature increases.

Front

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

Back

Pressure and volume are inversely related; as one increases, the other decreases, provided temperature remains constant.

Front

What is the absolute zero temperature in Kelvin?

Back

Absolute zero is 0 K, which is equivalent to -273.15 °C.

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

The new volume will be 100 mL, calculated using Charles's Law.

Front

What is the formula to convert Celsius to Kelvin?

Back

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

Front

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

Back

The Kelvin scale is used in gas laws because it starts at absolute zero, ensuring that temperature values are always positive.

Front

How do you find the new volume of a gas when its temperature changes?

Back

Use Charles's Law: V1/T1 = V2/T2. Rearrange to find V2: V2 = V1 * (T2/T1).
