Question

A vessel contains 100 liters of a liquid X. Heat is supplied to the liquid in such a fashion that, Heat given = change in enthalpy. The volume of the liquid increases by 2 liters. If the external pressure is one atm, and 202.6 Joules of heat were supplied then, [U - total internal energy]

Accepted Answer

Correct answer: D. (d) ∆H = heat given. So, process is isobaric. w = – P_ext (∆V) = – 1 × 2 litre.atm = – 202.6 J Hence, q = 202.6 J = ∆H. and ∆E = q + w = 0.
