Conway · Answer 1

Q=585000 kJ

Explanation:

Given Data

W (Work) = 603000 kJ

ΔU (Change in total internal energy) = -1.80*10⁴ kJ

Q (Heat Supplied) = ?

Solution

First Law of thermodynamic:

The first law of thermodynamics states that energy can neither be created nor destroyed, but only converted between various forms. For a closed system, we may write the change in internal energy as:

ΔU=Q-W

Q=ΔU+W

Q = - 1.80*10⁴+603000

Q = 585000 kJ
