# Change in Internal Energy Calculator, Formula, Internal Energy Calculation

## Change in Internal Energy Calculator:

Enter the values of torque, t(N.m) applied and angle of rotations, d(ϴ)(rad) to determine the value of work done by torque, Wt(J).

 Enter Change in Internal Energy: J Enter Change in Heat Energy: J Result – Work Performed by the System: J

## Change in Internal Energy:

The Change in Internal Energy dU(J) in Joules is Equal to the Change in Heat Energy q(J) in Joules to Addition of the Work Performed by the System w(J) in Joules.

The Equation of Change in Internal Energy can be written as,

dU(J) = q(J) + w(J)

Here,

dU(J) = Change in Internal Energy in Joules

q(J) = Change in Heat Energy in Joules

w(J) = Work Performed by the System in Joules

### Change in Internal Energy Calculation:

1)Calculate the Change in Internal Energy and given for Change in Heat Energy = 18J , Work Performed by the System = -8J.

dU = q + w

dU = 18 + (-8)

dU = 10 Joules.

2)Calculate the Work Performed by the System and given for Change in Heat Energy = 18J , Change in Internal Energy = 8Joules.
