Question

5.
It is desired to increase of the volume of a gas by 20% without changing the pressure. To what
temperature, the gas must be heated if the initial temperature of the gas is 27°?​

Answer 1

Answer:

87 ℃

Explanation:

T1 = 27℃ = 300 °k

V2 = 0.2 V1 + V1 = 1.2 V1

by Charles law, (constant pressure)

V1/T1 = V2/T2

therefore

T2 = V2*T1/V1 = 1.2*300 = 360 °k

or T2 = 360 - 273 = 87 ℃

so the gas must be heated to 87 ℃
