Question

If a gas at a constant one atmosphere of pressure is heated from 27 C to 127 C what will be it's percentage increase in volume?

Answer 1

Answer #1

As PV = nRT

So

V = (nR/P)*T

And hence

V₁ = (nR/P)*T₁

V₂ = (nR/P)*T₂

dV = V₂ - V₁ = (nR/P)*(T₂ - T₁)

Hence fractional change = dV/V₁ = (T₂ - T₁)/T₁ = (400-300)/300 = 1/3 = 0.333 or 33.3%
