Question

The teacher puts a sugar cube into a container of warm water. Eventually the sugar cube is no longer visible. What type of change is this and why?

I think it is a physical change because the sugar cube disappears.

Answer 1

Dissolving sugar in water is an example of a physical change. Here's why: A chemical change produces new chemical products. In order for sugar in water to be a chemical change, something new would need to result.

Answer 2

[AI-generated answer — Explain Bot]

You are correct! The process of the sugar cube dissolving in warm water is indeed a physical change. A physical change occurs when the substance undergoes a change in its appearance but does not change its chemical composition. In this case, the sugar cube is breaking apart and dispersing its particles evenly throughout the water, resulting in its disappearance. However, the individual sugar particles still remain and have not transformed into a different substance. Therefore, the change is physical.
