Question:
Enthalpy "H" is defined as
Enthalpy "H" is defined as
Show Hint
Enthalpy is a state function that is used to measure the heat content of a system under constant pressure.
Updated On: May 5, 2025
- H = E - PV
- H = E + PV
- H = F - TS
- H = F + PV
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Enthalpy (H) is defined as the sum of internal energy (E) and the product of pressure (P) and volume (V), as represented by the equation H = E + PV.
