First Law of Thermodynamics

Equation and meaning

\[\Delta_{Q} = \Delta_{U} + \Delta_{W}\]

First Law of Thermodynamics Where : Q is the Total Heat,W is the Work Done,U is the Internal Energy,

Variables in this formula

Delta_Q — Delta Q
Enter this value unless it is the selected unknown.
Delta_U — Delta U
Enter this value unless it is the selected unknown.
Delta_W — Delta W
Enter this value unless it is the selected unknown.

How to use this calculator

  1. Leave one value emptyThe empty field is automatically treated as the unknown.
  2. Enter known values and unitsChoose N, kgf, dyn, SI or another compatible unit when available.
  3. Review the automatic answerThe result appears immediately and is substituted back into the formula to check the residual.
