The amount of ration that must the hiker consume to avoid reduction in the body temperature of 2.5 K as a result of heat loss needs to be determined. Concept Introduction: In thermodynamics , a reversible process can be defined as the process which can be reversed back to its original state. Hence in reversible processes, both the system and surroundings are returned to their initial states. In general, all reversible processes are ideal processes and cannot occur naturally. On the contrary, an irreversible process cannot come back to its initial condition. All spontaneous processes in nature are irreversible processes. In an adiabatic process, the heat change is zero therefore the work done will be equal to the change in the internal energy.
