A system is provided with 50Joules of heat and the work done on the system is 10joules. What is the change in the internal energy of the system in Joules?
Step 1: Given
Heat provided to the system, q = +50J
Work done on the system, W = +10J
Step 2: Formula used and calculation
change in internal energy = heat provided + work done
Hence, change in internal energy is 60J.
