ANSWER:

According to the FIRST law of thermodynamics,

ΔU= q + W (i)

Where, ΔU = CHANGE in internal energy for a process

q = heat

W = WORK

Given, q = + 701 J (Since heat is absorbed)

W = -394 J (Since work is done by the system)

Substituting the values in expression (i), we get

ΔU= 701 J + (-394 J) ΔU = 307 J

Hence, the change in internal energy for the given process is 307 J.
