The value of change in internal energy in joules for a system that loses 50J of heat and has 150J.?

The value of change in internal energyin joules for a system that loses 50J of heat and has 150J of work performed on it by the surrounding is.?

Answer:
Delta U = 100 J
Hi,

E (internal)= q + W

q= heat, W= work. so: E= -50 + 150...hopefully you can do that math. Is this for a physics class or chem class? Best of luck!
