Suppose you warm up 460 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 5 × 10⁴ 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 19°C to 85°C.

Part 1 (a) What was the change in the thermal energy of the water? AEthermal = the tolerance is +/-2% ] Attempts: 0 of 10 used SAVE FOR LATER SUBMIT AN: Part 2 (b) Taking the water as the system, how much energy transfer due to a temperature difference (microscopic work) was there across the system boundary? Q= the tolerance is +/-2% ] Part 3 (c) Taking the water as the system, what was the energy change of the surroundings? AE surroundings ] Attempts: 0 of 10 used SAVE FOR LATER SUBMIT AN
