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...

Consider a “standard engineer” that weighs 75 kg and takes in food with a caloric content of 500 Cal = 2.09 x 106 J. a) If this food were completely converted to heat, estimate the rise in the body temperature of the engineer. Assume the specific heat of the engineer is equivalent to that of liquid water, 4.18 J g^(–1) K^(–1) . b) If the heat were used to vaporize water from body tissue, what would be the mass loss...
