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.

<u>Answer:</u> The density of liquid is
<u>Explanation:</u>
We are given:
Mass of cylinder, = 65.1 g
Mass of liquid and cylinder combined, M = 120.5 g
Mass of liquid, =
To calculate density of a substance, we use the equation:
We are given:
Mass of liquid = 55.4 g
Volume of liquid = 49.3 mL = (Conversion factor:
)
Putting values in above equation, we get:
Hence, the density of liquid is
