yes dissolving sugar in a coffee is a physical change
in a chemical change a new substance will be formed, and the component of this substance will be different from the parent substance.
but in the case of sugar dissolving in coffee, mixture of sugar and coffee retain their respective properties. Moreover we can also separate the constituents from that mixture.and there is no new substance is formed
that would be physical... trust me on this ;-)
Yes it is because it is mixed in with the coffee and can't be pulled apart.
That is a physical cahnge, not a chemical change, because sugar remains the same chemical, whether in solid or dissolved form.
That is really no chemical change.
Physical
It is a physical change.
Sugar dissolving would be an example of a physical change. This is because it does not change chemically, so it is still sugar.
Dissolving sugar in hot water is a chemical change.
No, dissolving sugar in hot tea is a physical change, not a chemical change. The sugar molecules are still present in the tea and can be separated by processes like evaporation. The chemical composition of the sugar does not change during the dissolving process.
It is a physical change.
Physical
The coffee remains coffee, and the sugar is simply dissolved. Thus, it is a physical change.
yes, it is a chemical change.
The process of sugar dissolving in water is a physical change, not a chemical change. The sugar molecules are simply dispersing in the water, without undergoing a chemical reaction.
