![]() Therefore option E is the correct answer. This suggests that option D is incorrect.Į) Both entropy and enthalpy are state functions as they only depend on the initial and final state and not on the path. Therefore option C is incorrect.ĭ) The standard molar entropy of an element in its standard state is equal to zero. The above equation suggests that there is no direct relation between the entropy of surroundings and the enthalpy change of the system. It is very closely related to the Kelvin statement given just above. Hence option B is incorrect.Ĭ) The following equation shows the relation between Gibb's free energy (G), entropy (S), enthalpy (H), and temperature (T) - Not mentioning entropy, this principle of Planck is stated in physical terms. The greater the extent of irreversibilities during a process, the smaller the entropy generation. The performance of engineering systems is degraded by the presence of irreversibilities. (C) In a decision tree, entropy determines purity. (B) In a decision tree, the entropy of a node decreases as we go down the decision tree. Entropy generation can be used as a quantitative measure of irreversibilities. Which one of the following statements is TRUE for a Decision Tree (A) Decision tree is only suitable for the classification problem statement. Therefore option A is incorrect.ī) The sum of the entropy of the system and entropy of surroundings is greater than zero. Question: Which of the following statements are true Choose all that apply. Hence it is concluded that the entropy is not positive for all the reactions. For example, liquid water is converted into solid ice. ![]() Evans and Williams discussed the difficulties in measuring a true single. For example, solid ice is converted into water vapors.īut if the randomness of the system is decreased in a particular reaction, the entropy will be negative. Hence, the following statement is crucial to our interpretation of energy in. ![]() For example, the following illustration shows a classifier model that. ![]() A) If the randomness of the system increased in a particular reaction, the entropy will be positive. For example, a model that made 40 correct predictions and 10 incorrect predictions. ![]()
