The flow of the heat q at a constant pressure in the process is equal to the change in enthalpy based on the following equation. ΔH=q A relationship between q and ΔH can be defined if q is ...

The change in enthalpy (ΔH) is negative because the energy is being lost by the system (the heater) and gained by the surroundings. Understanding the concept of enthalpy means learning how energy is ...

Enthalpy; Definition, Importance And Applications: Enthalpy is the measurement of energy in a thermodynamic system. It is a fundamental concept in thermodynamics.
