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∘.
Part A: Calculate the energy absorbed from a climber's body ifhe eats 0.50 kg of -15∘C snow which his body warms to bodytemperature of 37∘C. Express your answer to two significant figuresand include the appropriate units.
Part B: Calculate the energy absorbed from a climber's body ifhe melts 0.50 kg of -15∘C snow using a stove and drink theresulting 0.50 kg of water at 2∘C, which his body has to warm to37∘C. Express your answer to two significant figures and includethe appropriate units.
