In determining the average rate of heating of a tank of 20% sugar syrup, the temperature at the beginning was 20°C and it took 30 min to heat to 80°C. The volume of the sugar syrup was 50 ft3 and its density 66.9 lb/ft3. The specific heat of the sugar syrup is 0.9 Btu lb-1°F-1. (a) Convert the specific heat to kJ kg-1°C-1. (b) Determine the rate of heating, that is the heat energy transferred in unit time, in SI units (kJ s-1)

A student living in a 4-m x 6-m x 6-m dormitory room turns on her 150-W fan before she leaves the room on a summer day, hoping that the room will be cooler when she comes back in the evening. Assuming all the doors and windows are tightly closed and disregarding any heat transfer through the walls and the windows, determine the temperature in the room when she comes back 10 h later. Use specific heat values at room temperature, and assume the room to be at 100 kPa and 15°C in the morning when she leaves.
