What causes the entropy to change when the solute dissolves in a solvent?
The solute becomes less ordered
When sugar is dissolved in water why does the total amount of each substance stay the same?
In an ideal world a solute (sugar) dissolves in a solvent (water) without altering the volume. This is not always 100% true. The solute dissolves into the interstices of the solvent. Interstices means the holes between molecules - like pouring sand into a jar of marbles.The volume does not seem to change as the interstices are filled with the solute.
What kind of chemical compound do salt in water form?
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
Is dissolving oxygen gas and water a physical change or chemical change?
Dissolving in water is a physical change.
When sugar dissolves in water is there a mass change?
No
Is iodine dissolves in alcohol a chemical or physical change?
Dissolving (as such) of solutes in a solvent is physical.
Why does Milo dissolve in hot milk?
it is a physical change not a chemical change. milo dissolves into hot milk because it is a super saturated solvent.
What causes the entropy to change when the solute dissolves in a solvent?
The solute becomes less ordered
How adding solute changes the properties of a solvent?
Solutes raise and lower the boiling points of solvents. :)
If something dissolves into something else will it change mass?
The mass of the solution will be equal to the mass of the solute plus the mass of the solvent. However, the total mass does not change.
Is solubility a physical or chemical propety?
Solubility is a physical property because it is related to a physical, not a chemical, change. When something dissolves, it does not change chemically. It is still the same compound/molecule, etc. when it was not dissolved in the solvent.
Do all properties change when one substance dissolves into another?
No, Because Technically its still the same substance.
How does an increase in surface area help a solute dissolve more quickly?
Not necessarily just changing the surface area causes the rate to change. Changing the ratio of surface area volume changes the rate at which a solute dissolves in a solvent. If the surface area is larger and the volume of a solute is smaller or the same, then the rate at which the solute dissolves in a solvent increases. If the surface area is smaller and the volume of the solute is larger or the same, then the rate at which the solute dissolves in a solvent decreases.
What is the differences between chemical and physical change?
A chemical change involves a change in a substance's chemical properties (characteristics that describe how it interacts with other substances).A physical change involves a change in a substance's physical properties(characteristics that describe certain features one can see with their 5 senses).

What are properties that change?
the properties that change are physical and chemical properties!!! :)
