Question

Give an account of the classification of matter.

Answer 1

 substance is a sample of matter whose physical and chemical properties are the same throughout the sample because the matter has a constant composition. It is common to see substances changing from one state of matter to another. To differentiate the states of matter at least at a particle level, we look at the behavior of the particles within the substance. When substances change state, it is because the spacing between the particles of the substances is changing due to a gain or loss of energy. For example, we all have probably observed that water can exist in three forms with different characteristic ways of behaving: the solid state (ice), liquid state (water), and gaseous state (water vapor and steam).

Answer 2

Answer:

• matter is an entity which occupies space and has mass
• as the nature of the particles and physical forces between them determine the nature of the matter, so matter can be in different forms or States.
• generally matter can be classified into 5 states as

1. solid state
2. liquid state
3. gaseous state
4. plasma state
5. Bose Einstein condensate

• solid state in which matter has a fixed shape and a fixed volume
• liquid is the state in which matter has a fixed volume but its shape varies according to the shape of the container.
• gaseous state is the state in which matter neither has a fixed volume nor fixed shape
• solid ,liquid and gases are the three basic or classical States of matter
