The enthalpy of a system is the same as its:

A. specific heat.

B. heat of reaction.

C. heat of combustion.

D. heat content.

Enthalpy is a measure of the total energy of a thermodynamic system. It includes the internal energy, which is the energy required to create a system, and the amount of energy required to make room for it by displacing its environment and establishing its volume and pressure.

SO the answer is heat of reaction

The answer for above statement:

D. heat content.

Explanation:

Enthalpy is a measure of the total energy of a thermodynamic system. It includes the internal energy, which is the energy required to create a system, and the amount of energy required to make room for it by displacing its environment and establishing its volume and pressure.

Heat content - (thermodynamics) a physical science amount adequate the interior energy of a system and the merchandise of its volume and pressure.
