Part A

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 $2100\frac{J}{k}g*C,$ the latent heat of fusion is $333k\frac{J}{k}g,$ the specific heat of water is $4186\frac{J}{k}g*C.$

Calculate the energy absorbed from a climber's body if he eats $0\mathrm{.}40$ kg of $-15C$ snow which his body warms to body temperature of $37C.$

Express your answer to two significant figures and include the appropriate units.

$Q_1=2\mathrm{.}1{10}^{5}J$

Part B

Calculate the energy absorbed from a climber's body if he melts $0\mathrm{.}40$ kg of $-15C$ snow using a stove and drink the resulting $0\mathrm{.}40$ kg of water at $2C,$ which his body has to warm to $37C.$
