A portable gasoline-powered generator produces electrical energy from gasoline. If the generator were 100% efficient (that is, 100% of the energy from the fuel burned is converted to electrical energy), how much electrical energy in kWh would be generated from 5 gal of gasoline? The chemical potential energy in gasoline is 1.3 x 108 J/gal.
Answer:
6.5 10^8 J
Explanation:
chemical pe = 1.3 10^8 j/ gal
1.3 10^8 j/ gal (5 gal) = 6.5 10^8 j
the unit gal cancels out, leaving you with joules
