How does the hydrophobic effect contribute to changes in entropy within a system?
The hydrophobic effect increases entropy in a system by causing nonpolar molecules to cluster together in water, reducing the organization of water molecules around them. This leads to an increase in disorder and randomness, which is a key factor in the overall entropy change within the system.
When sugar dissolves es in water is the change in entropy positive or negative?
When sugar dissolves in water, the change in entropy is generally positive. This is because the sugar molecules become more dispersed in the solvent, increasing the disorder or randomness of the system.
Is entropy of water is higher than entropy of ice?
Yes, the entropy of water is higher than the entropy of ice because water is in a more disordered state compared to ice, which has a more ordered and structured arrangement of molecules. Entropy is a measure of disorder in a system, so the more disordered the state, the higher the entropy.
Will this entropy change by positive or negative water heating on a stove?
The entropy, S, will increase with temperature. If there's more kinetic energy in the pot, and the water molecules are flying around faster and faster as a result, there's more chaos and disorder, so a higher value of entropy.
What is it called when water vapor turns from a gas to a liquid?
Evaporation

When water becomes ice the entropy decreases does this contradict the second law?
No, because the entropy of the surroundings must increase more than the decrease in the water->ice transition, thus the net change in the entropy of the universe is positive, consistent with the second law.
When water freezes should the change in entropy be positive or negative and explain?
Please be aware that the change will be neither positive or negative. You see when "water" freezes the entropy will not change due the tempertaure of the area around it meaning the entropy will stay neutral. You are very welcome young man

How does the entropy of the system change when equal volumes of ethanol and water are mixed to form a solution?
The mixing of ethanol and water leads to an increase in entropy because the two liquids become more randomly dispersed at the molecular level compared to when they were separate. The increase in disorder allows for more ways to arrange the molecules, resulting in higher entropy of the system.

Does water vapor change into water when condensation occurs?
Yep. The very definition of 'condensation' is a state change from a gas to a liquid.
What did the water vapour change into?
The water vapor changed into liquid water through the process of condensation.
When salt is dissolved in water do you think the entropy of the system of salt and water increases or decreases?
When salt dissolves in water, the entropy of the system increases. This is because the salt molecules become surrounded by water molecules, leading to a more disordered state compared to the separate salt crystal and water molecules.
What is meant by entropy?
Entropy is a measure of the amount of disorder a system has. More accurately the amount of work that can be extracted from a system. The more entropy a system has the less work that can be done. 1kg of steam at 500 degrees can do lots more work than a kilo of warm water. Entropy always increases in a closed system. Entropy is why everything eventually breaks down.
