Gas molecules have fewer constraints on their location, than liquid molecules. Molecules in a liquid have to remain in contact with the other molecules of the liquid, and are limited to a specific volume. Gas molecules can go anywhere, they are not connected to anything. So with more possible locations, gas molecules represent a state of higher entropy or disorder.

What describes the phases of water Water expands as it changes from a solid to a liquid?
the entropy of water is higher than the entropy of ice.
Is entropy of water is higher than entropy of ice?
Entropy of water is higher than ice due randomness in the water molecule
Is greater than the entropy of a liquid?
gas
Can entropy effect osmosis?
In a nutshell, yes. The water will go from a higher concentration to a lower concentration to increase the entropy of the lower concentration area. The increase in entropy of the lower concentration area would be greater than the loss of entropy of the higher concentration giving you a NET increase in total entropy.
Is entropy is greater at higher trophic level than a lower level?
False
What happens to liquid water when it boils?
imagine that you are heating a pan of tap water on a cooker and taking the temperature of the water with a thermometer every two minutes until after the water has boiled
Which has a higher entropy a hot water or a cold water?
Entropy is the measure of disorderness. Hot water --> more energy --> less stable --> more disorderness (than Cold water). Therefore, Entropy of Hot water is greater than that of Cold water.
What is the difference between a reaction that happens spontaneously and a reaction that doesn't?
The difference can be clarified by entropy (the second rule of thermodynamics).The reaction is more spontaneous with higher entropy, for the reactions that occur spontaneously the entropy is higher than for the ones that do not.
If comparing a solid liquid or gas phase of H20 which has the highest entropy?
entropy is greater the more possible arrangements for energy there are, which increases as the molecules become more mobile, so entropy is high in a gas, lower in a liquid, and lowest in a solid.
Why is entropy of saturated liquid lower than saturated vapor for any pure substance?
Because to perform the change of state from the saturated liquid to saturated vapor ( at constant presure ) you have to add heat in the amount of the substance's evaporation latent heat Qev . At constant pressure, temperature will stay fixed at its saturation temperature and the increase in entropy will be (delta S)ev = Qev/Tsat where (delta S)ev is the entropy increment. Tsat is the saturation absolute temperature of the substance. And so the saturated vapor entropy is (delta S)ev larger than the saturated liquid entropy.
Wich reactions would have an increase in entropy?
A gas typically increases the entropy much more than the increase in moles.
How do you predict delta s?
delta s (change in entropy) is positive when.... -you go from a solid to a liquid -you go from a liquid to a gas -when you go from a solid to a gas -when there are more mols of products than mols of reactant the change in entropy is negative when the reverse of the above happens
