__ 16. Technician A says that gasoline has a higher energy content per volume than diesel. Technician B says that ethanol has a higher energy content per volume than gasoline. Who is correct? a. Technician A b. Technician B c. Both Technician A and Technician B d. Neither Technician A nor Technician B

The correct answer is d. Neither Technician A nor Technician B.<br /><br />Gasoline does not have a higher energy content per volume than diesel. In fact, diesel fuel has a higher energy content per volume compared to gasoline. This is because diesel fuel has a higher density and a higher cetane number, which means it can produce more energy per unit of volume when burned.<br /><br />Similarly, ethanol does not have a higher energy content per volume than gasoline. Ethanol has a lower energy content per volume compared to gasoline. This is because ethanol is a biofuel that is derived from plant-based sources, and it has a lower energy density than gasoline.<br /><br />Therefore, neither Technician A nor Technician B is correct in their statements.
