Homework Answers
A and B are correct.
The actual problem:-
Q = W + ∆E
= -380 J - 10 J
= -390 J
So absolute value of heat = 390 J
and heat is out of the system because it's negative.

Learning Goal Internal Energy of an ideal gas The internal energy of a system is the energy stored in the system. In an ideal gas, the internal energy includes the kinetic energies (translational and rotational) of all the molecules, and other energies due to the interactions among the molecules. The internal energy is proportional to the Absolute Temperature T and the number of moles n (or the number of molecules N). n monatomic ideal gases, the interactions among the molecules...
