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
Which one of the following processes produces a decrease in the entropy of the system? Which one of the following processes produces a decrease in the entropy of the system? mixing of two gases into one container boiling water to form steaь melting solid lead into liquid lead precipitation of AgCl(s) from Ag+(aq) and Cl−(aq) ions in solution dissolution of MgCl2(s) in water
Which of the following processes would you expect to produces the greatest increase in the entropy of a pure substance that is heated from absolute zero to a temperature somewhat above its boiling point. heating the liquid melting the solid heating the gas heating the solid vaporizing the liquid
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...
