In a certain chemical process, a lab technician supplies 292 J of heat to a system. At the same time, 68.0 J of work are done on the system by its surroundings. What is the increase in the internal energy of the system?

The increase in the internal energy of the system is 360 Joules.

Explanation:

Given that,

Heat supplied to a system, Q = 292 J

Work done on the system by its surroundings, W = 68 J

We need to find the increase in the internal energy of the system. It can be given by first law of thermodynamics. It is given by :

So, the increase in the internal energy of the system is 360 Joules. Hence, this is the required solution.
