- For each of the following processes, tell whether the entropy of the system increases, decreases, or remains constant.
- Melting one mole of ice to water at 0°C
- Freezing one mole of water to ice at 0°C
- Freezing one mole of water to ice at -10°C
- Freezing one mole of water to ice at 0°C and then cooling it to -10°C

entropy is a measure of disorder .If freedom of movement is high entropy would be high.In solid state ,particles can not move freely.hence entropy is small .where as in gaseous state entropy is maximum due to high degree of freedom.entropy increases in the following order.
solid < liquid <gas
1 melting. ice --> water = entropy increase
2 freezing .water-----> ice= entropy decrease
3. freezing water ---> ice at -10 c = entropy decrease
4. freezing= entropy decrease
Thank you

Indicate whether the entropy of the system increases or decreases for each of the following processes. Include a BRIEF explanation. Make up a process for (d) and indicate if the entropy of the system increases or decreases in that process, and provide a brief explanation as well. a) Water boiling at 100.0°C b) 2H2(g) + O2(g) ---> 2H2O(g) c) liquid water freezes at 0.0°C d) e) water vapor expanding from 1.0L of volume to 2.0L of volume f) mixing 10mL...

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...
