Charles's Law (5.1.3)

Question 1

• Charles’s law states that for a given amount of gas at constant pressure, the
volume is directly proportional to the temperature in kelvins.

Answer 1

• Charles’s law states that for a given amount of gas at constant pressure, the
volume is directly proportional to the temperature in kelvins.

Question 2

• All gases theoretically go to zero volume at absolute zero (0 K).

Answer 2

• All gases theoretically go to zero volume at absolute zero (0 K).

Question 3

Charles’s law states that for a given amount of gas
at constant pressure, the volume is directly
proportional to the temperature in kelvins. As the
temperature increases, the volume increases.
This can be stated mathematically as V ∝ T.
Rearranging this expression yields V/T = constant.
Since the volume divided by the temperature is
constant, the volume divided by the temperature at
an initial condition (Vi/Ti) will equal the volume
divided by the temperature at a final condition
(Vf/Tf). This relationship can be used to solve for Vi,
Ti, Vf, or Tf, given the other three variables.
All gases theoretically go to zero volume at a
temperature of –273.15˚C. This temperature is
referred to as absolute zero, and is the basis of the
Kelvin temperature scale. On the Kelvin scale,
absolute zero is 0 kelvins.
