Three hundred (300) moles of aluminum needs to be heated by 39
degrees Celsius. The heater that will be used in the process is
connected to circuit that provides 41 amperes of current and has a
resistance of 6750 milliohms.
The heating process takes 53 seconds to complete.
Aluminum has a molecular weight of 27 grams per mole and a
specific heat of 53.6 calories per pound-mass degree Fahrenheit
.
Determine the efficiency of the heater, expressed as a
percentage .
