$(a)$ Define matter and write its three states.
$(b)$ Explain how these states of matter arise due to variation in the characteristics of the particles.
$(b)$ Explain how these states of matter arise due to variation in the characteristics of the particles.
(N/A) Anything which has mass and occupies space is called matter.
Three states are: Solid,liquid,and gaseous.
$(b)$ These states arise due to variation in the characteristics of the particles,specifically:
$(i)$ Interparticle space: The distance between particles is minimum in solids,more in liquids,and maximum in gases.
$(ii)$ Interparticle force of attraction: The force is strongest in solids,moderate in liquids,and weakest in gases.
$(iii)$ Kinetic energy of the particles: The kinetic energy is minimum in solids and maximum in gases,which influences the movement of particles.
