Question

How many types of matter are classified ? Explain both of these

Answer 1

The three states of matter are the three distinct physical forms that matter can take in most environments:solid, liquid, and gas. In extreme environments, other states may be present, such as plasma, Bose-Einstein condensates, and neutron stars

1)
A solid is a sample of matter that retains its shape and density when not confined. The adjective solid describes the state, or condition, of matter having this property. The atom s or molecule s of matter in the solid state are generally compressed as tightly as the repulsive forces among them will allow

2)
A liquid is a sample of matter that conforms to the shape of a container in which it is held, and which acquires a defined surface in the presence of gravity. ... When a liquid is cooled, the atoms or molecules lose kinetic energy. If the temperature becomes low enough, the liquid becomes a solid. Water is a good example.

3)
A gas is a sample of matter that conforms to the shape of a container in which it is held and acquires a uniform density inside the container, even in the presence of gravity and regardless of the amount of substance in the container

Answer 2

A matter is said to be an object which occupies some place and which must have some mass.

Explanation:

Depending on the particles found in the substance, they can be divided into two parts -

1. Pure matter

2. Impure matter

1. Pure matter: Substances in which only one type of particle or component or component is present, that is, substances which are composed of only one type of element particles are called pure matter.

Examples: iron, oxygen, water, gold etc.

2. Impure substances: Substances in which more than one type of particles or components or components are found, that is, substances which are made up of more than one type of element particles are called impure substances.

Examples: soil, air etc.
