153g of boiling water (temperature 373K, heat capacity 4.2J/g/K) are poured into an aluminum pan whose mass is 1040g and initial temperature 311K (the heat capacity of aluminum is 0.9J/g/K). After a short time, what is the temperature of the pan? Tfinal - Submit Answer Tries 0/8 What simplifying assumptions did you have to make? Select all that are True. ☐ The thermal energy of the water doesn't change. ☐ Energy transfer between the system (water and pan) and the surroundings was negligible during this time. ☐ The thermal energy of the aluminum doesn't change. ☐ The heat capacities for both water and aluminum hardly change with temperature in this temperature range. Submit Answer Tries 0/2 Next, you place the pan on a hot electric stove. While the stove is heating the pan, you use a beater to stir the water, doing 35000J of work, and the temperature of the water and pan increase to 416.2K. How much energy transfer due to a temperature difference was there from the stove into the system consisting of the water plus the pan? Submit Answer Tries 0/8
