Aportable 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 1.3 108 j/gal.

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.
