Is water evaporating a chemical change?
Water evaporating is only a physical, not a chemical change because the water can be brought back easily to its original state where as burning a match is a chemical change.
Is copper sulphate dissolves in water a physical or chemical change?
A physical change is different from a chemical change in two ways:1) In a physical change no new substances are made; in a chemical change new substances are made.2) A physical change can be easily reversed; a chemical change cannot be easily reversed.Dissolving copper sulphate in water does not produce a new substance. The copper sulphate solution is a mixture, not a pure substance.Also, by evaporating the water you can easily get the copper sulphate back again.So, dissolving copper sulphate is a physical change.Sometimes, though, when water is added to copper sulphate, it reacts with the water to form copper sulphate pentahydrate, which is a new compound. This would be a chemical change, but actually dissolving it is indeed a physical change only.See these sites for more information:http://www.bbc.co.uk/schools/ks3bitesize/science/chemistry/chem_react_2.shtmlhttp://www.chem4kids.com/files/matter_chemphys.html
Why isn't dissolving sugar a chemical change?
Because the sugar stays sugar and the molecules themselves are unchanged, it does not change into another substance. Also, the process can easily be reversed by the physical process of evaporating the water.
How sunlight effects ice?
Light is a form of energy that can easily convert into heat energy. Heat energy can change ice from its solid phase into its liquid form--- pure water.
When a kettle is boiled you can tell it is NOT chemical change because?
the change is easily reversed so it is a physical change not a chemical change
Is water a reversable change?
Yes, the boiling of water can be easily reversed by simply cooling the water vapor.
What is the matter that changes most frequently?
Water can go through three different states on this planet relatively easily. Water can change its different states easily.
Is frozen water a chemical or physical property?

What is the color of sodium in aqueous?
The sodium ion, Na+, has no color. You can observe this easily by dissolving table salt (NaCl) in water. The water does not change color.
How is a stream formed?
obstacles that can't be moved easily by water change the direction of the stream. i did this for my science project and its true.
