Question

The best definition of the enthalpy change is ___ the change in internal energy of a system when the pressure is constant and no work is done. the energy that is transferred into or out of a system because of a temperature difference when the pressure is constant and only PV work is done. the energy that is transferred into or out of a system when the pressure is constant and no work is done. the change in internal energy of a system when the pressure is constant. the change in internal energy of a system when the volume is constant.

Explanation / Answer

answer : the energy that is transferred into or out of a system because of a temperature difference when the pressure is constant and only PV work is done.

==============================

An enthalpy change is roughly equivalent to the distinction between the vitality used to break bonds in a compound response and the vitality picked up by the arrangement of new concoction bonds in the response. It depicts the vitality change of a framework at consistent pressure.
