Question

define matter.list any two properties of matter

Answer 1

Anything in the universe, which occupies space and has Mass is know as Mass.

For example:- Earth, humans, trees etc.

There are many Properties of matter:-

Mass, length, shape, color, density etc.


There are Five types of matter:-

1.) Solid

2.) Liquid

3) Gas

4.) Plasma

5.) Bose-einstein Condensate (BEC)

Answer 2

There are two types of change in matter: physical change and chemical change. As the names suggest, a physical change affects a substance’s physical properties, and a chemical change affects its chemical properties. Many physical changes are reversible (such as heating and cooling), whereas chemical changes are often irreversible or only reversible with an additional chemical change.


Solid: A solid holds a definite shape and volume without a container. The molecules are held very close to each other
: A solid in which there is no far-range order of the positions of the atoms.


Liquid: A mostly non-compressible fluid. Able to conform to the shape of its container but retaining a (nearly) constant volume independent of pressure.Liquid crystal: Properties intermediate between liquids and crystals. Generally, able to flow like a liquid but exhibiting long-range order.


Gas: A compressible fluid. Not only will a gas conform to the shape of its container but it will also expand to fill the container.

Plasma: Free charged particles, usually in equal numbers, such as ions and electrons. Unlike gases, plasmas may self-generate magnetic fields and electric currents, and respond strongly and collectively to electromagnetic forces.
