Charles' Law

Front

What is Charles' Law?

Back

Charles' Law states that the volume of a gas is directly proportional to its temperature (in Kelvin) when pressure is held constant.

Front

What is the formula for Charles' Law?

Back

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.

Front

If a gas has a volume of 400 mL at 120°C, what is the new temperature if the volume increases to 700 mL?

Back

The new temperature is 414.75°C.

Front

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

Back

The volume of a gas decreases when its temperature decreases, provided the pressure remains constant.

Front

If the volume of a gas is 1.28 L at 39.0°C, what will be its volume at 8.0°C?

Back

The new volume will be 1.15 L.

Front

What is the relationship between temperature and volume in Charles' Law?

Back

As temperature increases, volume increases, and as temperature decreases, volume decreases.

Front

A gas occupies 200 mL at 600 K. What will its volume be at 300 K?

Back

The new volume will be 100 mL.

Front

What is the effect of constant pressure on a gas's volume and temperature?

Back

At constant pressure, the volume of a gas increases with an increase in temperature and decreases with a decrease in temperature.

Front

If a gas has a volume of 3.8 L at 25°C, what will be its volume at 57°C?

Back

The volume will be 4.21 L.
