An automobile engine generates 2283 Joules of heat that must be carried away by the cooling system. The internal energy changes by -2896 Joules in this process. Calculate w for the engine. This represents the work available to push the pistons in this process. w

The work done by the system (engine) is 5179 J

Explanation:

Given;

heat generated by the automobile engine, q = 2283 J

change in internal energy, ΔU = -2896 J

The work done by the system (engine) is given by the formula for estimating change in the internal energy of a system.

ΔU = q - w

-2896 = 2283 - w

w = 2283 + 2896

w = 5179 J

Therefore, the work done by the system (engine) is 5179 J
