Q
Q: What does the term 'enthalpy' refer to? (2020)
Solution: Enthalpy refers to the heat content of a system at constant pressure, defined as internal energy plus pressure times volume.
Steps: 5
Step 1: Understand that 'enthalpy' is a term used in thermodynamics, which is the study of heat and energy.
Step 2: Know that enthalpy measures the total heat content of a system.
Step 3: Remember that enthalpy is specifically measured at constant pressure, meaning the pressure does not change during the process.
Step 4: Learn the formula for enthalpy: it is the sum of internal energy (the energy contained within the system) and the product of pressure and volume (how much space the system occupies).
Step 5: Put it all together: Enthalpy = Internal Energy + (Pressure × Volume).
