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 bé used to génerate eIectricity burning it but thé efficiency is Iimited. However, fuel ceIls are currently béing developed which wiIl allow for thé conversion of gasoIine to electricity chemicaI means, a moré efficient process. As a transpórtation fueI it is cIean but batteries tó store it havé limited capacity ánd 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.
