An eager scientist on a hot summer day needs to determine how much ice to buy. She has a cooler which is filled with 38 cans of soda at a temperature of 87.7∘F. Each can has a mass of 408 g. The scientist wants the temperature of the drinks to be 40.8∘F. If there is no heat lost by the cooler and ignoring any heat lost to the soda containers, what mass ?ice of ice needs must she add to her cooler? Assume the temperature of the ice is 32.0°F.

HINT:The latent heat of fusion for ice is 80.0 cal/g,the specific heat of water is 1.00 cal/g⋅∘C and the specific heat of the soda is 0.900 cal/g⋅∘C and there are 454 grams per pound.

    (33%) Problem 3: Warm blooded animals are homeothermic that is, they maintain an approximately constant body temperature. (For humans it's about 37°C.) When they are in an environment that is below their optimum temperature, they use energy derived from chemical reactions within their bodies to warm them up. One of the ways that animals lose energy to their environment is through radiation. Every object emits electromagnetic radiation that depends on its temperature. For very hot objects like the sun, that...
