The term in the first law of thermodynamics which is involved in raising the temperature of the water in a jar by violently shaking the jar.

Answer to Problem 1FTD
Explanation of Solution
The first law of thermodynamics states that the change in internal energy of a system depends on the net
The law implies that there are two ways to vary the temperature and hence the internal energy of a system. They are either by transfer of heat or by work. The transfer of heat requires a temperature difference.
In shaking the jar, there is no temperature difference involved and hence heat is not involved in the process. Shaking the jar vigorously is doing mechanical work.
Conclusion:
Thus the term in the first law of thermodynamics which is involved in raising the temperature of the water in a jar by violently shaking the jar is
