GJ 3 m costelectricity hr costelectricity 27.778 GJ b) The electrical energy can directly be converted to other forms of energy whereas the coal and gasoline would typically need to be converted to heat and then into some other form of energy before being useful. The obvious advantage of coal is that it is cheap if it is used as a heat source. Otherwise it is messy to handle and bulky for tranport and storage. It can be used to generate electricity burning it but the efficiency is limited. However, fuel cells are currently being developed which will allow for the conversion of gasoline to electricity chemical means, a more efficient process. As a transportation fuel it is clean but batteries to store it have limited capacity and are heavy. T t 273.15 lnPsat ln (Psat) Array of functions used Mathcad. The strategy depends on age of the child, and on such unpredictable items as possible financial aid, monies earned the child, and length of time spent in earning a degree. The electric power supplied to the motor must equal the work done the motor plus the heat generated the motor.
