properties of matter
with activity
Answers
Answer:
1)matter is made up of particles.
Activity
●Take 100ml beaker with water and ●mark the level of water.
●Dissolve some sugar or salt in it.
●observe any change in water level.
observation= we observe that salt, sugar absorbed throughout the water and there is no change in water level .
conclusion =matter is made up of particle and has intermolecular space between them .
2)particle of matter are small in size .
●Take 2-3 crystal of potassium permagnet and dissolved in 100 ml water .
●take out approximate 10 ml of this solution and put into another 90 ml of clear water .
●keep dilution the solution 5-8 times.
observation =with every dilution throughout the colour became light but colour is still visible.
conclusion= there will be millions of tiny particles in just one crystal of potassium permanganate which keep on dividing themselves into smaller and smaller particles .
3)particle of matter are continuosly moving.
●put an unlit incense stick in a corner of your room how close do you have to go it to take it smell.
now light the incense stick what happened ?do you get smell at distance?
observation =when incense stick is unlit we can't smell the fragrance of it but when we lit the incense stick we get smell at a distance.
conclusion = particle of matter are continuously moving .
