Charles' Law - Volume and Temperature

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

How do you convert Celsius to Kelvin?

Back

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

Front

What happens to gas particles when temperature increases?

Back

When temperature increases, gas particles move faster and spread out further, resulting in an increase in volume.

Front

What is the formula for Charles' Law?

Back

The formula for Charles' Law is V1/T1 = V2/T2.

Front

What is STP in terms of temperature and pressure?

Back

STP (Standard Temperature and Pressure) is defined as 0°C (273.15 K) and 1 atm pressure.

Front

If a gas occupies 200 L at 27°C, what is the temperature in Kelvin?

Back

The temperature in Kelvin is 300.15 K (27 + 273.15).

Front

What is the new volume of a gas if it is cooled from 27°C to -33°C?

Back

The new volume is 160 L when calculated using Charles' Law.

Front

True or False: Colder gas particles are closer together than hotter gas particles.

Back

True.

Front

If a gas occupies 3.50 L at 80°C, what is the new volume at 30°C?

Back

The new volume is 3.00 L when calculated using Charles' Law.

Front

What does it mean for volume and temperature to be directly proportional?

Back

It means that as one increases, the other also increases, and vice versa, when pressure is constant.
