Enthalpy of a system is defined as the mass of the system - m - multiplied by the specific enthalpy - h - of the system and can be expressed as:
H = m h (1)
so: 3] Sum of internal energy and product of pressure and volume.
My answer is 3 - Sum of internal energy and product of pressure and volume

By definition, the enthalpy of the system is the sum of the internal energy of the system plus the product of the pressure of the gas in the system times its volume. .... Use your experience with ice, water, and steam to predict which of the following ...
3] Sum of internal energy and product of pressure and volume.
Option3
The Enthalpy is the preferred expression of system energy changes in many chemical, biological, and physical measurements, because it simplifies certain descriptions of energy transfer. It cannot be calculated directly and thats why we should calculate it by knowing the sum of the internal energy plus the product of pressure and volume.
