QUESTION:
What happens to the internal energy of a system when mechanical work is done on it? What happens to its temperature?
ANSWER:Solution 11RQ Step 1 of 2: According to first law of thermodynamics, the heat energy supplied to the system is used to change in internal energy of the system and the remaining will be used to do the work on/by the system. Q= U ± W Solving for change in internal energy, U = Q W Where U is change in internal energy, Q is the heat supplied and W is the work done on/by the system.
