How well can you apply Charles's law to this sample of gas that experiences changes in pressure and volume? Assume that pressure and number of moles of gas are constant in this problem.

As temperature increases the volume of given amount of gas increases while pressure and number of moles remain constant.

Explanation:

According to the charle's law,

The volume of given amount of gas is directly proportional to the temperature at constant pressure and number of moles of gas.

Mathematical expression:

V ∝ T

V = KT

V/T = K

When temperature changes from T₁ to T₂ and volume changes from V₁ to V₂.

V₁/T₁ = K V₂/T₂ = K

or

V₁/T₁ = V₂/T₂

Thus, the ratio of volume and temperature remain constant for constant amount of gas at constant pressure.
