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.

Respuesta :

I think 702?  (1.3x108)x5?    

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
