An anesthetized patient is inadvertently left in a position where their legs remain crossed for the duration of a multi-hour case. Which specific combination of distinct peripheral nerve injuries is anticipated due to the overlapping contact points between the limbs?

(a) How much heat transfer is necessary to raise the temperature of a 0.200-kg piece of ice from −20.0ºC to 130ºC, including the energy needed for phase changes? (b) How much time is required for each stage, assuming a constant 20.0 kJ/s rate of heat transfer? (c) Make a graph of temperature versus time for this process. Note: Ice’s specific heat is 2090 J/(kg⋅ºC) and latent heat for water at 0ºC is 334kJ/kg.
