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? .
a) calculate the energy absorbed from a climber's body if he eats 0.90
kg of -15? c snow which his body warms to body temperature of 37? c.
b) calculate the energy absorbed from a climber's body if he melts 0.90
kg of -15? c snow using a stove and drink the resulting 0.90kg of water at 2? c, which his body has to warm to 37? c.
