What is crystalllization?
The process of recrystallization relies on the property that for most compounds, as the temperature of a solvent increases, the solubility of the compound in that solvent also increases. For example, much more table sugar can be dissolved in very hot water (just below the boiling point) than in water at room temperature. What will happen if a concentrated solution of hot water and sugar is allowed to cool to room temperature? As the temperature of the solution decreases, the solubility of the sugar in the water also decreases, and the sugar molecules will begin to crystallize out of the solution. (This is how rock candy is made.) This is the basic process that goes on in the recrystallization of a solid.
What effect does salt water have on ice?
Fresh-water ice will melt faster in salt water than it will in fresh water or in the open air. Ice forms when water molecules are cooled down enough to arrange into solid crystals. Salt will, basically, get between the water molecules and make it harder for them to form crystals.
How does the temperature of a liquid effect how much sugar will dissolve?
I assume that you mean 'dissolves in water'. The answer is yes, very much so. The higher the temperature of the water, the quicker the sugar dissolves. The reason for this is very simple. As the temperature increases, water molecules move more quickly as they have more energy. They are therefore more likely to collide with and 'attack' the sugar crystals, causing sugar molecules to separate from each crystal and disperse throughout the water forming a sugar solution.
Can you use ice melt salt in a water softener?
Be careful of what you put in your water softener.The water softeners work by ion exchange... I.E. Exchanging heavy ions with lighter ions.Typically people fill the softeners with highly pure NaCl or KCl (sodium or potassium chloride).Your ice melt (assuming it is Sodium Chloride (salt)) based, would probably work, but it may not have the same purity as the salt for the water softener.I suppose you can think of it this way... if you let your dog drink out of mud puddles, why don't you drink out of mud puddles?
What type of rock cannot float on water?
Virtually all types of rock will sink in water. The only rock that can float on water is pumice.
Why do you have to melt sugar to make rock candy?
You dont. When you boil it in water, the sugar dissolves. Then let cool and evaporate and provide a crystallization seed, e.g. a thread. The sugar will cristallize out in large crystals as rock candy.
Does rock candy melt in water?
No. Rock candy dissolves in water, which is different from melting.
What sugar makes the largest rock candy?
about 100 tea spoons of sugarlol
What kind of stones melt when it is put into the water?
No stone/rock melts in water. It may erode over time, but does not melt. Salt as a mineral will dissolve in water.
What are the materials for rock candy?
sugar and water......boil sugar and water drop in a string let evaporate
How does sugar become rock candy?
sugar becomes rock candy when it is added with water. Once it is added with water you wait till the water evaporates thus having the sugar be left behind. Once the sugar is left be hind it hardens and forms into hard crystals we know today as rock candy.
How do you dissolve rock sugar in water?
To dissolve rock sugar in water, first crush the sugar into smaller pieces to speed up the dissolving process. Then, heat the water to a higher temperature (near boiling) and stir the sugar in until it completely dissolves. Alternatively, you can let the sugar sit in cold water for some time, stirring occasionally until it dissolves.
A student first dissolves sugar in water then evaporates the water to make rock candy The sugar water is an example of?
When a student dissolves sugar in water and then evaporates the water to make rock candy it is an example of a mixture. In science a mixture refers to the combination of different qualities.
Which environmental factors cause solid rock to melt?
High temperatures, high pressure, and the presence of water can cause solid rock to melt. As temperatures and pressures increase within the Earth's crust and mantle, rocks can begin to melt and form magma. The presence of water lowers the melting point of rock by aiding in the breakdown of minerals.
What are the science concept to rock candy?
rock candy is formed in a supersaturated solution of sugar & water.
Can lava melt rock in the mountain?
Underground molten rock, called magma, does melt some of the surrounding rock.
How does the composition of the magma effect the temperature at which it solidifies?
When fluids such as water combine with rock, the composition of the rock changes, which lowers the melting point of the rock enough to melt it.
