In the first segment of the chapter Physical and Chemical Changes, we will learn about Physical properties and changes.
What are Properties of matter?
Properties of matter around us are the specific qualities which define that particular matter. For example, a diamond is radiant, a metal sheet is hard, oil is slippery
But, substances have many properties.
To study the properties of any matter, they are divided into two broad categories:
- Physical properties
- Chemical properties
What are Physical properties?
Physical literally means the body of an object. Physical properties are, therefore, the properties that can be seen, or felt by us.
What are Physical changes?
Physical properties are subject to changes. The changes that alter the appearance of the matter are known as Physical changes.
Change in colour, shape or size, and the state of matter are all examples of physical changes. Another common example of physical changes is crystallisation. It is the process of formation of crystals. Crystals are solid forms having a specific arrangement of atoms and molecules.
Physical changes are reversible.
For example, a piece of metal hammered into a sheet can be melted to get its original form.
