i think its cos the sugar cube releases the oxygen that has been trapped inside it when it dissolves

What is weathered water?
It is when you put a sugar cube in water it dissolves.
How is the sugar cube look like a sedimentary rock?
A sugar cube looks like a sedimentary rock because, it has small and tiny particals such as those tiny crystals you see in a sugar cube. A sedimentary rock on the other hand, is composed of small sediments, like a sugar cube is composed of small particals and crystals.
When Ice floating on water melts what happens to liquid level and why?
When ice cube is submerged on water...The upthrust created on the ice cube by water is equal to the weight of the displaced water...when the ice cube is melting its volume changes but its weight remains the same and its exactly equal to the weight of displaced water when the ice cube was frozen...therefore the 'volume of of melted water' fits exactly to the 'volume of displaced water when the ice cube was frozen'... So the water level does not change! -Shenal K Mendis ;)
Crush a sugar cube into a powder what part of the rock cycle does this represent?
It represents the erosion.
How does a sugar cube dissolve in water?
Sugar cubes (and salt, and many other materials) dissolve in water because water is a powerful solvent. Properties of water molecules cause them to break down the crystalline structure of a sugar cube.Polar MoleculesWater molecules are polar, meaning that one part of the molecule has a slightly positive electric charge, and one part has a slightly negative electric charge. Sucrose molecules also have a part that carries a slight negative charge.Crystalline BondsThe bonds that hold a sugar cube together in a crystalline structure are fairly weak and rely on the sugar molecules being in contact with each other.Water Breaks the Crystalline BondsThe attraction between the negatively charged part of the sugar cube and the positively charged part of the surrounding water molecules pulls the sucrose away from the crystalline structure.Water Surrounds the SucroseThe negatively charged part of the sucrose molecule pulls in water molecules from all directions. They form a shell around the sucrose, preventing it from rejoining the crystalline structure. This layer of water molecules is called the hydration shell.Removing the WaterWhen the water is removed, through evaporation for example, the sucrose molecules come into contact with each other again and reform their crystalline bonds. They are not changed chemically in any way by the process of absorption.
What is an example of a sugar cube disaolving?
Dissolving dissolving! Watch your grammar. The best example is sugar cube dissolving in a water. Best way to dissolve it is to smash it, put it in water and then stir it.
A sugar cube dissolving in water is an exam ple of?
Sugar's dissolveable qualities.
What is the dependent variable for sugar cube dissolving?
temperature of water. :) and youre welcome(:
a sugar cube dissolving in water?
yes
Is a cube of surgar dissolving in water a physical or chemical change?
This is a physical change the chemical composition of the sugar does not change
Is a cube of sugar dissolving in coffee considered osmosis?
Yes, the "passive moving" of water across the membrane is considered osmosis.
What will have the highest rate of solubility a sugar cube in boiling water a sugar cube in room temperature water a sugar cube in refrigerated water?
solubility generally increases on heating. so sugar cube in boiling water will dissolve fastest.
What are the green features of the water cube in Beijing?
BUBBLES BUBBLES The bubbles are made of EFTE which is a green feature.
What happens if sugar mixed with water is frozen?
its like a sugar cube. you have sugar and water then it freezes. then the water is sweet. so therefore its a sugar cube
Does the level of water rises When sugar is mixed in water?
if a lump ofsugaris dropped into a glass ofwaterit graduallydisappears.....Dissolving sugar in water is a physical change. You can tell this because if you were to dissolve the sugar in water and then let the water evaporate, the sugar would still be left. All of the components that you started with are still there, even if you can't see them.
How does temperature affect the dissolving rate of a sugar cube?
Higher temperatures mean the molecules are moving more rapidly. This will speed up the process of disolving a sugar cube, because there is more activity.
Suger cube dissolves in water is it chemical or physical change?
Dissolving in water is a physical change.
