Q
Q: In thermodynamics, what does the term 'enthalpy' (H) represent? (2020)
Solution:
Enthalpy (H) represents the heat content of the system at constant pressure, defined as H = U + PV.
Steps: 5
Show Steps
Step 1: Understand that enthalpy is a term used in thermodynamics, which is the study of heat and energy.
Step 2: Know that enthalpy is represented by the letter 'H'.
Step 3: Realize that enthalpy measures the total heat content of a system.
Step 4: Remember that enthalpy is specifically measured at constant pressure.
Step 5: Learn the formula for enthalpy: H = U + PV, where 'U' is the internal energy, 'P' is the pressure, and 'V' is the volume of the system.
