Enthalpy Calculator

Formula: Enthalpy(QP) = Δ E + P Δ V

Internal energy of Products = Joules
Internal energy of Reactants = Joules
Pressure of system = pascals
Volume of Products = cubic meters
Volume of Reactants = cubic meters

Enthalpy = Joules

Enthalpy Calculator is a free online tool that displays the Enthalpy for the given equation. CoolGyan online enthalpy calculator tool makes the calculation faster, and it calculates the enthalpy of the system in a fraction of seconds.

How to Use the Enthalpy Calculator?

The procedure to use the enthalpy calculator is as follows:

Step 1: Enter the internal energy, volume and pressure in the input field

Step 2: Now click the button ”Calculate Enthalpy” to get the result

Step 3: Finally, the enthalpy of the system will be displayed in the output field

What is Meant by Enthalpy?

In Physics, enthalpy is defined as the sum of the internal energy and the product of the pressure of the given thermodynamic system. It represents the state of the system. It is not a measure of heat transfer. In short, enthalpy is used to measure the energy of the system. Enthalpy is expressed by the letter ”H”. Thus, the formula to calculate enthalpy is given by:

Enthalpy, H = U + PV


U – Internal Energy

P – Pressure

V – Volume
