Q4: the average heat evolved by the oxidation of food in an average adult per hour per kilogram of body weight is 7.20 ୩୎ ୩୥ ୦୰. assume the weight of an average adult is 62.0 kkg. suppose the total heat evolved by this oxidation is tranderred into the surroundings over a period of 1 week. calculate the entropy change of the surroundings associated with this heat transfer. assume the surroundings are at 293k.

The entropy change of the surroundings associated with this heat transfer is 255.9J/K

Explanation:

The heat evolved by the oxidation of food is 7.2J/Kg.h thus, multiplying the heat by the weight of the person and by the time the total heat (q) is obtained. In this case, the weight is 62.0Kg and a weak has 168 hours.

The entropy change of the surrounding associated with this heat transfer can be calculated by the ratio between the heat exchanged and the temperature.
