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୰.
1 answer:
Answer:
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.

Answer:
is the total displacement (volume) of the submarine.
Explanation:
Mass of water carried by submarine at 1000 ft depth = m = 2100 kg
The density of seawater at 1000 ft depth = d =
Volume of the water displaced = V= ?
Total displacement of the submarine = Volume of the water displaced = V
is the total displacement (volume) of the submarine.
