  1. The total energy of a system
  2. The heat content of a system at constant pressure
  3. The work done by a system
  4. The change in internal energy

Questions & Step-by-Step Solutions

In thermodynamics, the term 'enthalpy' is defined as: (2022)
  • 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.
