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 1 ami and 202.6 joules of heat were supplied, then [U= total internal energy] |
| A. | \[\Delta U=0,\,\Delta H=0\] |
| B. | \[\Delta U=+202.6J,\,\Delta H=+202.6J\] |
| C. | \[\Delta U=-202.6J,\,\Delta H=-202.6J\] |
| D. | \[\Delta U=0,\,\Delta H=+202.6J\] |
