Question

A vessel contains 100 litres 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 litres. If the external pressure is one atm, and 202.6 Joules of heat were supplied then, [$U\to$ total internal energy]:-

• A. $\Delta U=0,\Delta H=0$
• B. $\Delta U=+202.6J,\Delta H=+2.206J$
• C. $\Delta U=-202.6J,\Delta H=-2.206J$
• D. $\Delta U=0,\Delta H=+202.6J$

Answer 1

The correct option is D $\Delta U=0,\Delta H=+202.6J$
