Which of the following is a True Statement? PLEASE EXPLAIN ANSWER
A) It is possible for heat to flow spontaneously from a hot body to a cold one of from a cold one to a hot one, depending on whether or not the process is reversible or irreversible.
B) It is impossible to transfer heat from a cooler to a hotter body.
C) It is not possible to convert work entirely into heat.
D) The second law of thermodynamics is a consequence of the first law of thermodynamics.
E) All of these statements are false.
E. Statements A-D are false.
To determine why all the statements A-D are false, we need to analyze each statement individually.
A) This statement is false because heat flowing spontaneously from a hot body to a cold one violates the second law of thermodynamics. According to the second law, heat always flows from a hotter body to a colder body in a spontaneous process.
B) This statement is also false because it contradicts statement A. As mentioned earlier, heat cannot spontaneously flow from a cooler body to a hotter body. It violates the second law of thermodynamics.
C) This statement is false. According to the first law of thermodynamics, energy cannot be created or destroyed, but it can be converted from one form to another. Work is a form of energy, and it can be completely converted into heat.
D) This statement is false because the second law of thermodynamics cannot be derived solely from the first law. The first law focuses on energy conservation, while the second law deals with the direction of energy flow and the concept of entropy.
Based on the explanations above, we can conclude that all the statements A-D are false.
