Enthalpy of a system is also called as _________?
- A
Entropy
- B
Work function
- C
Total heat content
- D
Internal energy
Enthalpy is the measurement of energy in a thermodynamic system. The quantity of enthalpy equals to the total content of heat of a system, equivalent to the system's internal energy plus the product of volume and pressure.
Entropy is the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work. Thus this option is incorrect.
The minimum energy required for free electrons to come out of the metal surface is called the work functions of that metal, thus this option is incorrect.
Enthalpy is the measurement of energy in a thermodynamic system. The quantity of enthalpy equals to the total content of heat of a system, equivalent to the system's internal energy plus the product of volume and pressure.
Internal energy is the inherent microscopic energy of a system associated with the random motion of its molecules. Thus this option is incorrect.
