Entropy increases means disorder is increasing. So melting increases the entropy.
Option (A) is correct.
In all other options entropy is decreasing.
Below is entropy order;
Gas > liquid > solid
The process that leads to an increase in entropy is A melting B freezing condensation D...
Considering these phase transitions: melting, condensation, vaporization, freezing, sublimation, which one (ones) of the given phase transitions is (are) endothermic? Lütfen birini seçin: O a. condensation and freezing only b. melting and sublimation only O C. sublimation, melting, and vaporization only O d. melting and vaporization only
Entropy (S) The second factor involved in determining whether or not a process is spontaneous is the change in randomness or entropy (AS). Entropy is represented by the symbol S. Again, experience can help us understand the relationship between entropy and spontaneous processes. If we look at the two drawings below, we can predict which picture represents the stack of marbles "before" and after they are bumped. We expect the stack of marbles (less random, lower entropy) to be the...
Label the phase changes shown in the diagram below. Freezing Condensation Sublimation Vaporization Deposition Melting
Which of the following processes should lead to an increase in entropy of the surroundings? Select as many answers as are correct however points will be deducted for incorrect guesses. Select one or more: Vaporization of liquid water Freezing of water into ice Condensation of water vapour Melting of ice into liquid water An exothermic reaction An endothermic reaction Check

O Whipped cream O shampoo O trail mix o fog QUESTION 15 What type of macromolecule in food (carbohydrate, fat, protein) contains the MOST energy per gram? Protein Fat Carbohydrate
22. Choose the process(s) that lead(s) to an increase in entropy of the system. Treat all gases as ideal. A) The pressure of 1 mole of Oz is doubled through compression at a constant temperature. B) CO2 is expanded to 10x its original volume. C) A glass of water cooling down to a lower temperature. D) NH3(g) + HCl(g) → NH4Cl(s) E) 2H2(1) + O2(1) → 2H2O(g)
For a single substance at atmospheric pressure, classify the following as describing a spontaneous process, a nonspontaneous process, or an equilibrium system. Drag the appropriate items to their respective bins. Bins: Spontaneous Process, Nonspontaneous process, and Equilibrium System 1) solid melting below its melting point 2) liquid vaporizing below its boiling point 3) gas condensing below its condensation point 4) solid and liquid together at the melting point with no net freezing or melting 5) liquid vaporizing above its boiling...
