Is it a physical change when a sugar and water solution is evaporated?
no
When salt water has evaporated did it undergo a physical or chemical change?
When salt water has evaporated, it has undergone a physical change since the salt and water both retain their chemical configuration, only have changed their form.
Is sugar dissolving a chemical or phyical change?
Sugar dissolving in water is a chemical change because sugar is Sucrose which in aqueous solution is broken down into Glucose and Fructose.
Is sugar dissolves in warm water chemical change?
No, the dissolving of sugar in warm water is not a chemical change; it is a physical change. When sugar dissolves, it breaks down into its individual molecules, but its chemical structure remains unchanged. This process is reversible, as the sugar can be recovered by evaporating the water.
Is concrete setting a physical or chemical change?
It would be both. It's a physical change because it is changing state and a chemical change because water is being evaporated.
Is making Sugar into sugar syrup a physical change or chemical change?
Unless you overdo it and carmelize it, it is a physical change. A typical process is to dissolve a large amount of sugar into hot water (physical change - the sugar is still sugar and the water is still water; they do not react. If the sugar-water is not syrupy enough, you can boil off some of the water (still a physical change). If you overdo it though, you will begin to caramelize the sugar. If the sugar is sucrose, it breaks down into fructose and sucrose along with a host of other side reactions that condense, isomerize, dehydrate, fragment, polymerize, and otherwise chemically change the original sugar. Caramelization is definitely a chemical change, but it is not necessary to make syrup.
If dish of sugar and water solution is left in the sun after a few days the solution has disappeared and a white residue remains on the dish Has a physical or chemical change taken place explain?
Yes, A physical change has taken place. The water has evaporated and left the sugar. Neither substance has changed its identity. GOOD LUCK ON YOUR TEST!
Is sugar dissolving in water physical change or chemical?
It is a physical change as you can change it back.
How could you prove that dissolving table salt in water is a physical change or not a chemical change?
well you know its not a chemical change when you see the salt dissolving because if your were to put something else like sugar then it would be a chemical change because the sugar would just float right to the bottom and stay there but salt would go around in the water and start dissolving.
Is dissolving sugar in water a physical changes?
Yes, dissolving sugar in water is a physical change. If you let the water evaporate, you the sugar will be left behind. Evaporation is a physical process, not chemical.-No, It is a Chemical change.
When you dissolve solid sugar into water this new solution will taste sweet the sugar went through a chemical change?
Dissolving sugar in water is a physical change, not a chemical change. The sugar molecules are still the same chemical substance before and after dissolving; they have simply spread out in the water. The sweet taste comes from the sugar molecules interacting with your taste buds, not from a chemical change taking place.
When Sugar dissolves in hot water a physical or chemical change?
When sugar dissolves in hot water, it is a physical change. This is because the sugar molecules are simply mixing with the water molecules but are not undergoing a chemical reaction to form new substances.
