A rapidly spinning paddle wheel raises the temperature of 200 mL of water from 21 degrees Celsius to 25 degrees Celsius. What is the amount of work done in this process, and how much heat is transferred?

the work is done by the friction force. All the work will go to increase the internal energy of the water.
Q=mC∆θ=3360 J
Where C=4200J, m=1000×200×10^-6=0.2 kg
There are ''No'' heat transfer in the process.
