**Question:**Suppose 19.0 J of heat is added to a system and the net amount of work done by the system is 7.0 J. How does the internal energy of the system change?**Options:**- ○ It increases by 12.0 J- ○ It decreases by 26.0 J- ○ It increases by 19.0 J- ○ It decreases by 9.0 J- ○ There is no change**Explanation:**This question is based on the First Law of Thermodynamics, which states that the change in internal energy of a system (\(\Delta U\)) is equal to the heat added to the system (\(Q\)) minus the work done by the system (\(W\)):\[\Delta U = Q - W\]**Calculation:**Given:- Heat added, \(Q = 19.0 \, \text{J}\)- Work done, \(W = 7.0 \, \text{J}\)\[\Delta U = 19.0 \, \text{J} - 7.0 \, \text{J} = 12.0 \, \text{J}\]Thus, the internal energy of the system increases by 12.0 J.
