Questions and Answers

According to Charles' Law, what happens to the volume of a gas if the Kelvin temperature is increased?

  • The volume of the gas decreases
  • The volume of the gas increases (correct)
  • The amount of gas decreases
  • The pressure of the gas increases

If the pressure and the amount of gas are held constant, what happens to the volume of a gas as its Kelvin temperature decreases?

  • The volume of the gas decreases (correct)
  • The volume of the gas increases
  • The amount of gas decreases
  • The pressure of the gas increases

In Charles' Law, if the pressure and the amount of gas are held constant, what is the relationship between the volume and Kelvin temperature?

  • The volume is inversely proportional to the Kelvin temperature
  • The volume is directly proportional to the pressure
  • The volume is inversely proportional to the pressure
  • The volume is directly proportional to the Kelvin temperature (correct)

Charles' Law - Volume-Temperature Relationship

As the Kelvin temperature of a gas increases, its volume also increases, assuming pressure and amount of gas remain constant.

Direct Proportionality in Charles' Law

The volume of a gas is directly proportional to its Kelvin temperature when pressure and amount of gas are held constant.

Charles' Law - Cooling a Gas

If you decrease the Kelvin temperature of a gas, its volume will also decrease, provided pressure and amount of gas remain constant.

Charles' Law Equation

The relationship between volume (V) and Kelvin temperature (T) in Charles' Law can be expressed as: V1/T1 = V2/T2.

Study Notes

Charles' Law

  • If the Kelvin temperature is increased, the volume of a gas also increases, provided the pressure and amount of gas are held constant.
  • If the Kelvin temperature is decreased, the volume of a gas also decreases, provided the pressure and amount of gas are held constant.
  • The volume of a gas is directly proportional to its Kelvin temperature, as long as the pressure and amount of gas are held constant.
  • Charles' Law describes the relationship between volume and temperature when pressure and amount of gas are held constant.
  • Understanding the relationships covered by each gas law, including Charles' Law, is important because it allows us to predict and explain the behavior of gases in different situations.
