What Is Enthalpy Change?
Enthalpy is a thermodynamic quantity representing the total heat content of a system at constant pressure. This calculator estimates the change in enthalpy when a substance’s temperature changes, assuming no phase change.
The Formula
ΔH = m × Cp × ΔT, where m is mass, Cp is the specific heat capacity at constant pressure, and ΔT is the temperature change.
This is a simplified sensible-heat calculation for general educational purposes; it does not account for latent heat during phase changes.
