Calculate AEfor a system that absorbs 599,0 kJ of heat from its surroundings
and does 3510 kJ of work on its surroundings.

Answer 1

Answer:

-2911 kJ

Explanation:

Step 1: Given data

• Heat absorbed by the system (Q): 599.0 kJ (By convention, when the systems absorbs heat, Q > 0)

• Work done by the system on the surroundings (W): -3510 kJ (By convention, when the systems does work on the surroundings, W < 0)

Step 2: Calculate the change in the internal energy (ΔE)

We will use the following expression.

ΔE = Q + W

ΔE = 599.0 kJ + (-3510 kJ) = -2911 kJ
