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) at constant pressure.

Front

How do you convert Celsius to Kelvin?

Back

To convert Celsius to Kelvin, add 273.15 to the Celsius temperature.

Front

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

Back

According to Charles' Law, the volume of a gas increases as its temperature increases, provided the pressure remains constant.

Front

If a gas has a volume of 200 mL at 27°C, what is its volume at -33°C?

Back

The volume will decrease to 160 mL.

Front

What is the formula for Charles' Law?

Back

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

Front

If the volume of a gas is 65 L at 35 K, what will it be at 40 K?

Back

The new volume will be 74.3 L.

Front

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

Back

Volume increases with an increase in temperature and decreases with a decrease in temperature.

Front

What is the initial volume of a gas if it expands to 0.92 L at 176°C from 0.6 L at 293 K?

Back

The initial volume is 0.6 L.

Front

How does pressure affect the volume of a gas according to Charles' Law?

Back

Charles' Law assumes constant pressure; if pressure changes, the relationship may not hold.

Front

What is the Kelvin equivalent of 50°C?

Back

50°C is equivalent to 323 K.
