Interpretation:
The new volume of the gas have to be calculated.
Concept Introduction:
Charles’s law: The volume of a given amount of gas is proportional to its temperature (in K) of the gas at constant pressure.
The relationship between volume of a gas and temperature is expressed as-
Charles’s law can also be expressed in mathematical form as-
In the above equation, V1 is initial volume and T1 is initial temperature, while V2 is final or new volume and T2 is final or new temperature.

Answer to Problem 18A
The new volume of the gas is 548.66 mL.
Explanation of Solution
Data given: V1 =500 mL
T1 = 25 °C = (273 + 25) K = 298 K
T2 = 54 °C = (273 + 54) K = 327 K
