Increasing temperature favors dissolution when?
solute dissolves more rapidly in hot water
Does kinetic energy help sugar dissolve more quickly?
The kinetic energy is only very slightly involved in dissolving sugar. What is important is that stirring mixes the solution and the liquid close to the sugar will not get saturated because it is being mixed with all the other liquid. the grains of sugar will present more surface area to the solvent (they will be mixed up in it and not settle to the bottom of the mixing vessel) thus the grains will dissolve faster if they are stirred vigorously. The heat energy added to the solution from stirring plays a very minor role.
3 ways to increase the rate of solvation?
1. Stir or shake the solution 2. Expose more surface by crushing a solid solute. 3. Warm the solution.
How do you separate a solid and liqiud that form a solution?
There are many ways to separate a solid from a solution, one way is to let the contents of the solution settle or to separate, after separation, from a solution of the residue in evaporable materials and/or solvents with the addition of up to 20% by weight of high-boiling hydrocarbons that are inert under evaporation conditions of the evaporable materials, heating the mixture to evaporation temperature under vacuum, whereby the evaporable materials evaporate, are drawn off and condensed, and the residue is obtained as a free-flowing solid, the residue solution being introduced onto a stirred bed of granular solid material kept at the evaporation temperature.
A drink is made up of mostly water small amount of sweet powder is stirred in using a spoon the water in this solution is the?
Sounds like a glass of Kool-Aid or Tang to me (or your favorite generic).In scientific terms, the water is a solvent. The flavored powder is a solute.
How do temperature and stirring affect the solubility of a solute in a solvent?
if the water is hot,the solvent will dissolve faster and when it gets stirred it will dissolve even faster than when it wasn't. but if the water is cold it will dissolve slower than hot water even when stirred.
Increasing temperature favors dissolution when?
solute dissolves more rapidly in hot water
What does stirred mean?
it mean that it is soul but it is stirring in joys
A small quantity of a salt is stirred into a liter pf water until it dissolves in the resulting mixture the water is?
Although this question is quite ambiguous, stirring a small quantity of salt in water until it dissolves will produce an unsaturated solution as long as the salt is water soluble. Stirring a small amount of a water-insoluble salt in water may produce a saturated solution if the quantity of salt dissolved in the water is such that no more can be dissolved.
Sugar dissolves when stirred into water the sugar is the what the water is the what and the sweetened water is the what?
Sugar is solute Water is the solvent Sweetened water is the solution
How do you use stirring in a sentence?
Its basically telling that you are stirring (stir).
What is the difference between stirring committee and steering committee?
Stirred...not shaken...
Why microwave cooking is quicker and why I am the food stirred?
Microwaves cook (heat) the outsides of the food first. So stirring part way through the cooking time allows a more even heating.
Do solids dissolve quicker if the water is stirred?
Yes, stirring help the dissolution.

What are the effects of stirring on supercooling?
Stirring prevents super cooling by inducing nucleation
Can a solution be filtered if it was stirred?
yes
