High-altitude mountain climbers do not eat snow, but always meltit first with a stove. To see why, calculate the energy absorbedfrom a climber's body under the following conditions. The specificheat of ice is 2100 J/kg?C?, the latent heat of fusion is 333kJ/kg, the specific heat of water is 4186 J/kg?C?.
A) Calculate the energy absorbed from a climber's body if heeats 0.45 kg of -15?C snow which his body warms to body temperatureof 37?C. Express your answer to two significant figures and includethe appropriate units.
B) Calculate the energy absorbed from a climber's body if hemelts 0.45 kg of -15?C snow using a stove and drink the resulting0.45 kg of water at 2?C, which his body has to warm to 37?C.Express your answer to two significant figures and include theappropriate units.
