Answer:

-2911 kJ

Step-by-step 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
