When the liquid is cooled the movement of its particles will decrease and they will pack themselves into a rigid shape thus forming a solid. Freezing: In this process a liquid changes into a solid on cooling.The particles of the solid will start changes moving faster on heating and break away from their rigid pattern thus making a liquid. Melting: In this process a solid changes into a liquid on heating.Question: Describe how the states of matter change in terms of the movements of tiny particles.Īnswer: In terms of the movement of particles the changes in states of matter will be as follow: Gases: In gases particles are very loosely packed and they can easily flow from one place to another.This is the reason liquids can take the shape of the container they are poured into. Liquids: In liquids particles are not as closely packed as in solids.Solids: In solids the particles are very closely packed and because of this mostly solids have fixed shape.The arrangement of particles results in three states of matter:. Question: Explain in what way is the arrangement of particles related to the states of matter.Īnswer: All matter is made up of every small particles. On heating the movement of particles increases. Question: How does heating and cooling affect the movement of particles?Īnswer: On cooling the movement of particles decreases Question: List any three processes to show that matter changes from one state to another.Īnswer: The three processes to show that matter changes from one state to another are :. Question: What makes liquids take the shape of the container they are poured in?Īnswer: Liquids take the shape of the container they are poured in because the particles are not as tightly packed as in solids. Question: What is matter made up of?Īnswer: Matter is made up of very small particles. Answer: Any substance that has mass and occupies space.
