On a cold winter morning you step outside to get into your car and drive to work. Your car's windshield is covered with ice at $-17\mathrm{.}3C.$ If the area of the windshield is $1\mathrm{.}40m^2$ and it takes $2\mathrm{.}02{10}^{5}J$ of heat to melt the ice, how thick was the ice covering the windshield? The latent heat of fusion of ice is $334k\frac{J}{k}g,$ the specific heat of ice is $2092\frac{J}{kg*C}$ and its density is $917k\frac{g}{m^3}.$

Following vigorous exercise, an $80\mathrm{.}0-kg$ person's body temperature is $37\mathrm{.}6C.$ At what rate in watts must they transfer thermal energy to reduce their temperature to $37\mathrm{.}0C.in\mathrm{.}26\mathrm{.}0$min, assuming their body continues to produce energy at the rate of $150$ W $?$ The specific heat of the human body is $3500\frac{J}{kg*C}.$
