An ice cube Ts=0C is brought in contact with human skin having Cp= 3.7106J/m3C,k=0.293W/mC, and T(t=0)=37C for a total elapsed time of t=300s. The surface area of heat transfer is 100cm2. Use the solution for transient conduction through a semi-infinite slab with prescribed surface temperature to determine the amount (J) of heat transfer from the skin to the ice during this elapsed time
