__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.
