Calculate Change in Enthalpy (dH)





Formula

The formula to calculate the Change in Enthalpy (dH) is:

\[ dH = dU + dP \cdot dV \]

Where:

Definition

Example

Let's say the change in internal energy (dU) is 500 J, the change in pressure (dP) is 1000 Pa, and the change in volume (dV) is 0.02 m³. Using the formula:

\[ dH = 500 + (1000 \cdot 0.02) = 520 \]

So, the Change in Enthalpy (dH) is 520 J.
