If amount of heat given to a system be 50 J and work done on the system be 15 J, then change in internal energy of the system is

View answer and explanation

Correct option: C

65 J

Option C (65 J) is correct because the change in internal energy is calculated by adding the heat given to the system and the work done on the system according to the first law of thermodynamics.
