Concept explainers
Interpretation:The five examples of physical change needs to determined and explained.
Concept Introduction: The change that affects only the form of a chemical substance but the chemical composition remains same is same said to be physical change.
Explanation of Solution
The five examples of physical changes are:
- Melting of an ice cube:
- Dissolving sugar in water:
- Evaporation of rubbing alcohol:
- Boiling of water:
- Melting of wax:
It is a physical change in which the
It is a physical change as the solid sugar molecules are separated by water and water never loses its properties as it can be recovered via evaporation of water.
When left uncovered, the rubbing alcohol evaporates quickly into the air that is it changes its state from liquid to gas but composition of alcohol remains same.
It is a physical change in which the state of matter changes from liquid to gas and the composition of substance remains same that is
It is a physical change in which the state of matter changes from solid to liquid and the composition of substance remains same.
