A system does 196 J of work on its environment and gains 40 J of heat in the process.
(a) What is the change in the internal energy of the system?
J

(b) What is the change in the internal energy of the environment?
J



I thought the answer would be +40 for the system and -40 for the enveironment sin the system gain 40 j of heat, but that is not the correct answer. What am I doing wrong.
