Question

Quizplus · Accepted Answer

Temperature is usually uniform throughout a cell, which means there is no temperature gradient to drive the transfer of heat energy into work. In thermodynamics, work can be extracted from a system only when there is a temperature difference that allows heat to flow from a hotter region to a cooler one.
