Question

1. which of the following is an example of a physical change? (1 point)

cooking a hamburger
dissolving sugar in water
boiling an egg
burning a match

Explanation:

A physical change is a change in which no new substances are formed. When sugar is dissolved in water, only the state of sugar changes (from solid to dissolved in liquid), and no new chemical substances are created. Cooking a hamburger, boiling an egg, and burning a match all involve chemical reactions where new substances are formed.

Answer:

dissolving sugar in water
