Boyles and Charles Law Review

Front

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

Back

The volume decreases (inverse relationship).

Front

What is the formula to convert Celsius to Kelvin?

Back

K = °C + 273.15

Front

If a balloon has a volume of 1.28 L at 39.0°C, what is the new volume at 8.0°C?

Back

1.15 L (using Charles's Law).

Front

What is Charles's Law?

Back

At constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin.

Front

What is Boyle's Law?

Back

At constant temperature, the pressure of a gas is inversely proportional to its volume.

Front

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

Back

Inverse relationship: as pressure increases, volume decreases.

Front

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

Back

Use Charles's Law: V1/T1 = V2/T2.

Front

What is the new volume of a gas if the initial volume is 65 L at 35 K and the temperature increases to 40 K?

Back

74.3 L (using Charles's Law).

Front

What is the Kelvin equivalent of 50°C?

Back

323 K.

Front

What type of relationship do temperature and volume have in Charles's Law?

Back

Direct relationship: as temperature increases, volume increases.
