Question

A piston at -37.0°C contains a gas that occupies a volume of 2.5 L. To what temperature would the gas have to be heated to increase the volume to 6.3 L at constant pressure?

Answer 1

answer and explanation

Charles's law tells use the relationship between volume and temperature of a gas by the equation

V1/T1 = V2/T2

from the data provided we find V2 by:

37/2.5 = V2/6.3

V2 = 93.2 degrees

the gas would have to be heated to 93.2 degrees to expand in volume to 6.3L
