Which of these statements regarding the storage materials is false? Choose from the choices below:       LP gas and gasoline has the same specific energy and thus are equally well suited as fuels for a vehicle.       The energy density of Li ion batteries is lower because it's another type of storage material.       Even though carbohydrates have a lower specific energy than hydrocarbon fuels, their energy density is higher because they are solids.       Hydrogen has the highest specific energy, but its energy density is quite low
