Suppose you warm up 540 grams of water (about half a liter, or about a pint) on a stove, and while this is happening, you also stir the water with a beater, doing 2multiply.gif104 J of work on the water. After the large-scale motion of the water has dissipated away, the temperature of the water is observed to have risen from 18°C to 82°C.

What was the change in the thermal energy of the water?

Taking the water as the system, how much energy transfer due to a temperature difference (microscopic work) Q was there across the system boundary?

Taking the water as the system, what was the energy change of the surroundings?
