thanks! :)-If the system gains, the sign is positive.If the system loses, the sign is negative.ΔE = work + heat = w + q = +281J -961J = -680J-Its best to ask a simple question first to test understanding of basic concepts.......
What is the internal energy change for the system if 961 joules of heat flows fro the system into the surroundings and 281 joules of work is done on the system by the surroundings?

please help, thanks! :)

If the system gains, the sign is positive.
If the system loses, the sign is negative.
ΔE = work + heat = w + q = +281J -961J = -680J

It's best to ask a simple question first to test understanding of basic concepts.
