Hi there.
00:03
In this question, we are trying to identify why the dissolving of sugar in water is a physical change.
00:09
So to do that, we need to define what a physical change is.
00:12
A physical change is any change in matter that does not produce a new substance.
00:37
It may appear different, but it still has the same chemical formula and the same properties.
01:01
Okay, so let's look at our answer options here.
01:05
Letter a says the chemical.
01:08
The chemical.
01:08
Composition of sugar changes.
01:11
Well, that is false.
01:11
That would not be a physical change.
01:13
That would be a chemical change if its chemical composition changes.
01:18
The next one says the water gets sweeter.
01:24
It's really the sugar in the water.
01:26
That is the sweetness.
01:27
So that is not describing the physical change.
01:30
We're looking for a change in the matter.
01:33
Letter c says the sugar changes from its solid state.
01:38
So we have sugar as a solid...
