Question

A piston uses 32 J of energy to do work as 68 J of heat are added to the cylinder of the piston. The change in internal energy of the system is ___ J.

Answer 1

36j

Step-by-step explanation:

Answer 2

Internal energy is defined as the energy associated with the random, disordered motion of molecules. It is denoted by U and calculated by the expression:

ΔU = Q - W

We calculate as follows:

ΔU = 68 J - 32 J
ΔU = 36 J
