Question

If water vapour is assumed to be a perfect gas,molar enthalpy change for vapourization of 1mol of water at 1 bar and 100degreeC is 41 kj mol^-1 calculate the internal energy when 1mol of water is vapourised at one bar pressure and 100degree C

Answer 1

Answer:

use q=n.c.dt

Explanation:

then from u=q+w
