Internal Energy of System Solution

STEP 0: Pre-Calculation Summary

Formula Used

Internal Energy of the System = Change in Heat Energy-(Work Done given IE)
U_WD = Q_d-(W_IE)
This formula uses 3 Variables

Variables Used

Internal Energy of the System - (Measured in Joule) - Internal Energy of the System all the energy within a given system, including the kinetic energy of molecules and the energy stored in all of the chemical bonds between molecules.
Change in Heat Energy - (Measured in Joule) - Change in Heat Energy is the sum of all these heat energies is the total energy the substance gains or loses.
Work Done given IE - (Measured in Joule) - Work Done given IE is the product of component of the force in the direction of the displacement and the magnitude of this displacement.

STEP 1: Convert Input(s) to Base Unit

Change in Heat Energy: 50 Joule --> 50 Joule No Conversion Required
Work Done given IE: -60 Joule --> -60 Joule No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

U_WD = Q_d-(W_IE) --> 50-((-60))

Evaluating ... ...

U_WD = 110

STEP 3: Convert Result to Output's Unit

110 Joule --> No Conversion Required

FINAL ANSWER

110 Joule <-- Internal Energy of the System
