PT #121-Boyle's and Charles' Laws

Front

What is Boyle's Law?

Back

Boyle's Law states that at constant temperature, the pressure of a gas is inversely proportional to its volume. If the pressure increases, the volume decreases, and vice versa.

Front

What is Charles' Law?

Back

Charles' Law states that at constant pressure, the volume of a gas is directly proportional to its absolute temperature (in Kelvin). If the temperature increases, the volume increases.

Front

How do you convert Celsius to Kelvin?

Back

To convert Celsius to Kelvin, add 273 to the Celsius temperature.

Front

If a gas occupies 500 ml at 0.971 atm, what will be its volume at 1.50 atm at constant temperature?

Back

323.6 ml.

Front

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

Back

The volume decreases.

Front

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

Back

The temperature decreases.

Front

What is the formula for Boyle's Law?

Back

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

Front

What is the formula for Charles' Law?

Back

V1/T1 = V2/T2, where V is volume and T is temperature in Kelvin.

Front

What is absolute zero in Kelvin?

Back

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

Front

If a gas has a volume of 852 mL at 298 K, what is the temperature for a volume of 945 mL?

Back

330.5 K.
