Change in Enthalpy Calculator

Enthalpy is a crucial concept in thermodynamics, representing the total heat content of a system. Calculating the change in enthalpy (ΔH) can be complex, but with this interactive calculator, you can quickly determine it. Simply input the change in internal energy (ΔU), change in pressure (ΔP), and change in volume (ΔV), and let the calculator do the rest.

How to Use the Change in Enthalpy Calculator

Calculating the change in enthalpy involves the following formula:

ΔH = ΔU + Δ(PV)

Where:

• ΔH = Change in Enthalpy (in Joules, J)
• ΔU = Change in Internal Energy (in Joules, J)
• ΔP = Change in Pressure (in Pascals, Pa)
• ΔV = Change in Volume (in cubic meters, m³)

Follow these steps to calculate ΔH:

1. Enter the value for ΔU in the input field labeled “Change in Internal Energy (J).”
2. Enter the value for ΔP in the input field labeled “Change in Pressure (Pa).”
3. Enter the value for ΔV in the input field labeled “Change in Volume (m³).”
4. Click the “Calculate ΔH” button.
