Calculate the energy absorbed from a climbers body

Reference no: EM13270241

High-altitude mountain climbers do not eat snow, but always melt it 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?C?, the latent heat of fusion is 333 kJ/kg, the specific heat of water is4186 J/kg?C?.

Part A Calculate the energy absorbed from a climber's body if he eats 0.70kg of -15?C snow which his body warms to body temperature of 37?C.

Part B Calculate the energy absorbed from a climber's body if he melts 0.70kg of -15?C snow using a stove and drink the resulting 0.70kg of water at 2?C, which his body has to warm to 37?C.
