Which of the following information is not derived from first law of th...
Explanation:
The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed, but it can be converted from one form to another. It is a fundamental principle in physics and is applicable to various thermodynamic processes.
a) Energy can neither be created nor be destroyed:
This statement is derived from the first law of thermodynamics. It implies that the total energy of an isolated system remains constant. Energy can only be transferred or converted from one form to another.
b) The total change in internal energy is equal to heat involved and work done in a process:
This statement is derived from the first law of thermodynamics. It is a mathematical expression of the conservation of energy. The change in internal energy of a system is equal to the heat added to the system minus the work done by the system.
c) During a process of energy conversion, some energy is lost as heat:
This statement is also derived from the first law of thermodynamics. It is a consequence of the fact that no energy conversion process is 100% efficient. Some energy is always lost in the form of heat due to various factors such as friction, radiation, and inefficiencies in the conversion process.
d) The randomness of the universe is always increasing:
This statement is not derived from the first law of thermodynamics. It is related to the concept of entropy, which is a measure of the disorder or randomness of a system. The second law of thermodynamics states that the entropy of an isolated system always tends to increase or remain constant. However, this law is not directly related to the first law of thermodynamics.
Therefore, option D is the correct answer as it is not derived from the first law of thermodynamics. The other options (A, B, and C) are all derived from the first law and are fundamental principles of thermodynamics.
