Question

High-attitude mountain climbers do not eat snow, but always melt first with a stove. To see why calculate the energy absorbed from a climber's body under the following conditions The specific heat of ice is 2100 J/kg the latent heat of fusion is 333 kJ/kg.C^10 the specific heat of water is 4186 J/kg C^10 Calculate the energy absorbed from a c tamper's body if he melts 085 kg of-15 degree C snow using a stove and drink the result 0.85 kg of water 2 degree C, which his body has to warm to 37 degree C Express your answer to two significant figures and include the appropriate units

Explanation / Answer

part b;

           Energy required to change 0.85 of kg of water at 2degree c to water at 35degreec

      =o.85*4.2kj/kg*(37-2)

     =124.9kj

      =1.2*10^5j
