The Delta H (Enthalpy Change) Calculator helps determine the change in enthalpy (ΔH\Delta HΔH) based on temperature, mass, and heat capacity. To use the Basic Calculator, enter Heat Capacity (J/g°C), Mass (g), and Temperature Change (°C). Leave Delta H (J) blank for automatic calculation, or alternatively leave any one field empty to solve for that specific value.

For a more comprehensive analysis, switch to Advanced Calculator mode and provide values for Average Heat Capacity (J/g°C), Total Mass (g), Initial Temperature (°C), and Final Temperature (°C). Upon calculation, Total Delta H (J) will display the enthalpy change based on the given values. Select Calculate to perform the calculation or Reset to clear all entries.

### Input Field Purpose
