What does the motion of chalk dust particles on water surface show about matter?

A student in Kakamega sprinkles chalk dust on the surface of still water in a basin. After a short while, the chalk particles start to move around slowly without being touched. What does this observation show about the nature of matter?   (1 mark)

Mary stirs a spoonful of salt into warm water until the salt is no longer visible. What does this show about liquid particles?

The image below shows Mary stirring a spoonful of salt into warm water. After some time, the salt is no longer visible. Using particle theory, explain why this happened.   (1 mark)

Ann pours juice from a bottle into a cup. The juice takes the shape of the cup. What does this show about the behaviour of liquid particles?

Ann wants to fill differently shaped glasses with juice. She notices that each time she pours juice into a new glass, the juice takes the shape of that glass. Using particle theory, explain why the juice behaves this way.   (1 mark)

Which property of gas particles allows them to fill the entire volume of any container?

At a bakery in Kisumu, the smell of freshly baked bread spreads throughout the entire room within minutes, even though the windows and doors are closed. Which property of gas particles best explains how the smell reaches every corner of the bakery? (1 mark)

John tries to compress a wooden block but fails. What does this tell us about the arrangement of particles in solids?

John tries to fit a wooden block into a smaller container by pressing it with his hands, but the block does not change shape. Using particle theory, explain why the wooden block could not be compressed.  (1 mark)

The image below shows smoke spreading in the air from a burning paper. What does this tell us about gas particles?

In a classroom experiment, paper is burned on a metal tray and smoke is seen rising and spreading across the room. After a short while, the smoke disappears from sight. Using particle theory, explain why the smoke spread and vanished.  (1 mark)

Why does the volume of salt solution become slightly less than the total of salt and water before shaking?

A cook in Eldoret pours 100 ml of water into a measuring cylinder and then adds 20 ml of salt. After shaking, the total volume reads about 115 ml instead of 120 ml. Why did the volume of the salt solution become slightly less than the total of salt and water before shaking?   (1 mark)
