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, W_t(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.

Answer

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.

Answer

dU = q + w

8 = 18 + w

w = -8Joules.
