Q
Q: In thermodynamics, the term 'enthalpy' is defined as: (2022)
Solution:
Enthalpy is defined as the heat content of a system at constant pressure, represented as H = U + PV.
Steps: 4
Show Steps
Step 1: Understand that enthalpy is a measure of heat content in a system.
Step 2: Know that this measurement is taken when the pressure in the system remains constant.
Step 3: Learn the formula for enthalpy, which is H = U + PV.
Step 4: In the formula, 'H' represents enthalpy, 'U' is the internal energy of the system, 'P' is the pressure, and 'V' is the volume.
