Q1. A 1200-Wiron is left on the ironing board with its base exposed to the air (Figure 1). About 90 percent of the heat generated in the iron is dissipated through its base whose surface area is 150 cm?, and the remaining 10 percent through other surfaces. Assuming the heat transfer from the surface to be uniform determine (a) the amount of heat the iron dissipates during a 1- hour period, in kWh and (b) the total cost of the electrical energy consumed during this 1-hour period. Take the unit cost of electricity to be $0.07/kWh. Iron 1200 W Figure 1

A mass of 7 kg undergoes a process during which velocity decreases from 32 m/s to 19m/s, while the elevation remain unchanged. The initial specific internal energy of the mass is 1.24 kJ/kg and the final specific internal energy is 2.08 kJ/kg. During the process, the mass receives 2 kJ of energy by heat transfer through its bottom surface and loses 0.8 kJ by heat transfer through its top surface. How much is the work in kJ? (hint: be consistent with units) ( 2 decimal places)
