Question

what is the change in energy (in J) for a system that lost J of heat to the surrounding, and did 150J of work

Answer 1

Change in energy Δu = 40 J

Step-by-step explanation:

Given:

System heat ΔQ = 150 J

Missing value of Lost heat ΔW = 110 J

Find:

Change in energy Δu

Computation:

Change in energy Δu = System heat ΔQ - Missing value of Lost heat ΔW

Change in energy Δu = 150 - 110

Change in energy Δu = 40 J
