Required information In an emergency, it is sometimes the practice of medical professionals to immerse a patient who suffers from heat stroke in an ice bath, a mixture of ice and water in equilibrium at 0°C, in order to reduce her body temperature. The average specific heat of human tissue at 20.0°C is 3.50 x 103 J/kg-K. The latent heat of fusion for water is 333.7 x 10 J/kg. A(n) 85.1-kg patient whose body temperature is 43.5°C was reduced to 37.0°C. If she is placed in a bath containing 5.70 kg of ice, what will be the ice remaining in the bath when her body temperature is 37.O°C? kg
