Question

Quizplus · Accepted Answer

Shale has the ability to yield large amounts of oil and gas when heated to a high temperature, with some sources citing up to 100 liters per ton of input. Therefore, it is likely that shale will yield at least 25 liters per ton when heated to 500°C. Biomass, natural gas, and light petroleum are not typically used in this process and are therefore not likely to be the correct answer.
