Question: Living organisms, as they grow, convert relatively simple food molecules into complex structures. Is this a violation of the second law of thermodynamics? Explain your answer.

Short Answer

Expert verified

No, this is not a violation of the second law of thermodynamics.

Step by step solution

01

Second law of thermodynamics

According to the second law of thermodynamics, natural processes progress toward a state of higher disorder or higher entropy.

02

Explanation for why this process does not violate the second law of thermodynamics

In the process of conversion, heat is generated, which maintains the body temperature. The growth of an individual from an individual cell to a matured person occurs from the energy providedby the breakdown of these food molecules.

In the method of development and growth and even throughout the mature life of an individual, waste commodities are excluded. The tiny molecules that persist as a result of metabolism are simple molecules without much order.

It signifies a relatively great disorder or entropy, which is in accordance with the second law.

Can you warm a kitchen in winter by leaving the oven door open? Can you cool the kitchen on a hot summer day by leaving the refrigerator door open? Explain.

(I) Solar cells (Fig. 15鈥�26) can produce about 40 W of electricity per square meter of surface area if directly facing the Sun. How large an area is required to supply the needs of a house that requires 24 kWh/day? Would this fit on the roof of an average house? (Assume the Sun shines about 9 h/day.).

Question:(I) A heat engine鈥檚 high temperature\({T_{\bf{H}}}\)could be ambient temperature, because liquid nitrogen at 77 K could be\({T_{\bf{L}}}\)and is cheap. What would be the efficiency of a Carnot engine that made use of heat transferred from air at room temperature (293 K) to the liquid nitrogen 鈥渇uel鈥�(Fig.15鈥�25)?

Question:(I) If an ideal refrigerator keeps its contents at 2.5掳C when the house temperature is 22掳C, what is its COP?

Which of the following possibilities could increase the efficiency of a heat engine or an internal combustion engine?

(a)Increase the temperature of the hot part of the system and reduce the temperature of the exhaust.

(b) Increase the temperatures of both the hot part and the exhaust part of the system by the same amount.

(c) Decrease the temperatures of both the hot part and the exhaust part of the system by the same amount.

(d) Decrease the temperature of the hot part and increase the temperature of the exhaust part by the same amount.

(e) None of the above; only redesigning the engine or using better gas could improve the engine's efficiency.
