Question:
The total heat content or energy level of a material is its
The total heat content or energy level of a material is its
Show Hint
Enthalpy ($H$) measures total thermal energy content; enthalpy changes ($\Delta H$) determine heating and cooling loads.
Updated On: Sep 15, 2026
- Specific Heat
- Thermal diffusivity
- Enthalpy
- Radiation
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Thermodynamic state functions quantify energy content and thermodynamic potential in food engineering systems.
Step 2: Detailed Explanation:
Enthalpy ($H = U + PV$) is the thermodynamic property representing the total heat content of a substance, accounting for internal molecular energy ($U$) and flow work ($PV$).
Specific heat is the energy required to raise unit mass by one degree, and thermal diffusivity characterizes the rate of temperature spread.
Step 3: Final Answer:
Hence, the total heat content or energy level of a material is its enthalpy.
