Question
Calculate the change in internal energy for each of the followingsystems: a. 100 joules of energy is added to a system that does 40 joules ofexternal work b. 15 joules of energy is removed from a system that has 50 joulesof work done on it. c. 150 joules of energy is added to a system that has 75 joules ofwork done on it. Calculate the change in internal energy for each of the followingsystems: a. 100 joules of energy is added to a system that does 40 joules ofexternal work b. 15 joules of energy is removed from a system that has 50 joulesof work done on it. c. 150 joules of energy is added to a system that has 75 joules ofwork done on it.Explanation / Answer
E = 100j – 40j
= 60j
E = -75j + 50j
=-25j
E = 150j + 75j
=225j
