a) List three characteristics of particles of matter. When we add some sugar or salt in a beaker45 containing water, after sometime the sugar or salt becomes invisible. Where does it go ?
What property of particle of mattert does it show?
b) How will you justify that ice water and steam are the three states of a substance and not different substances?

Three characteristics of particles of nature:
1)Particles of matter are continuously moving
2)Particles of matter have space in between them
3)Particles of matter attract each other.
When we add some sugar or salt in a beaker containing water, after sometime the sugar or salt becomes invisible. This is because the sugat or salt particles get arranged in between water molecules. This shows that there is space in between the particle.
b) Ice can be converted to water by giving heat. Water can be freeze to ice by reducing temperature so the starting ice is obtained only by change in temperature. Similarly water is also converted to steam by increase of temperature and get back again by decrease of temperature.In all the case starting is get back by change in physical condition. Therefore these are 3 states of matter.
