Consider the following four cases
i. A chemical process in which heat is absorbed.
ii. A change in which q = 30 J, w = 44 J.
iii A process in which a system does work on its surroundings with no change in q.
iv. A process in which work is done on a system and an equal amount of heat is withdrawn.
In how many of these cases does the internal energy of the system decrease?
O 0
O 1
O 2
O 3
O 4
