4:- What is volume?
Ans:- The amount of space that a substance occupies is called its volume.
The SI. unit of volume is cubic meter (m3).
The common unit of measuring volume is litre (L).
1litre = 1dm3
1litre = 1000 mL
1mL = 1cm3
5:- Is matter continuous or particulate?
Ans:- Matter is particulate. It is made up of particles.
6:- Prove that matter is made up of particles.
Ans:- When we dissolve sugar in water the water level doesnot rise but the sugar completely
dissolve into water because the particles of sugar get into the space between particles
of water, so we can say that matter is made up of particles.
