Question

350 J of heat is added to a system and 250 J of work is done by the system. What is the change in internal energy of the system?​

Answer 1

Answer:

$100j$

ΔU = UB – UA = q + w

Here q = 350 j and W = -250 j

Therefore, change in internal energy ΔU = 350 J -250 J = 100 J

Hence, the change in internal energy for the system is equal to 100 J
