The document explains the three states of matter: solids, liquids, and gases, detailing their properties and behaviors. Solids maintain shape and can be soft or hard, liquids take the shape of their container while maintaining volume, and gases fill available space with no fixed volume. The text discusses various examples and characteristics of each state, emphasizing the movement of particles and the interchangeable nature of states through heat and cooling.
SCIENCE - STATE OF MATTER (CLASS V - IGCSE BOARD)
- 3. STATES OF MATTER All types of matter are made up of extremely small particles.
- 4. SOLID LIQUID GAS MOLECULES ATOMS Matter is made up of tiny particles called molecules.
- 5. Scanning Tunnelling Microscope (STM) Molecules are always in a state of motion and even when inside matter, they never stop moving.
- 7. SOLID Arrangement of particles present in the solid. WOOD GLASS SAND ICE
- 8. COTTON CLAY Solids can also be soft. We can easily change the shape of soft solid by applying force or by squeezing them.
- 9. Sponges are special types of solids that have air spaces in them.
- 10. Solids exist in powder form. SAND SUGAR SALT
- 12. Fill their container completely?
- 15. DO YOU KNOW? Liquids take the shape of the container in which they are poured.
- 17. Pipes carry fluids from one place to another.
- 19. Observation • The level of water in both the containers are different. This shows that liquid does not have a shape of its own. It takes the shape of the container. • The volume of water remains the same in both the container.
- 22. Classificationofliquids Colour Odour Feel The most common example of a colourless and odourless liquid is water.
- 23. Shampoo – it is a colourful liquid and has its own smell.
- 24. Honey flows less easily than water and is sticky in nature
- 25. Milk is a white colour liquid. Petrol and kerosene have a property of catching fire. Cooking oil is an edible liquid. It can also catch fire easily.
- 27. GAS Gases can flow easily and take up all the available space.
- 28. Boiling water will turn into vapour on further heat. These vapours mix with the air present in the room. Gases completely fill the available space.
- 29. When air is filled into the balloon, we can see it grows bigger and bigger
- 30. This proves that gas occupies space and has weight..
- 31. Properties of gases • Gases do not have a fixed volume. • They are not visible. • They can flow more easily than liquid. • We cannot hold them with our hand.
- 33. L P G
- 34. • Choose the odd one out a) Milk b) Honey c) Sand d) Soft drink • I am a state of matter. I do not change my shape and cannot move around. I can be found everywhere around you. Who am i? • True or False a) Liquids are easy to compress. b) The particles of a gas are packed tightly together.
- 35. Water exists in all three states of matter. Solid Ice Liquid water Gaseous Vapour
- 37. States of matter are inter – changeable. HEAT COOL SOLID LIQUID HEAT GAS COOL
- 38. • Which of the following gases is compressed in cylinders and used as a fuel? a) Air b)Steam c) LPG d)None of the above • Which of the following is the correct characteristic of water? a) Water exists in all three states of matter. b)Water has odour. c) Water has taste. d)Water is blue in colour.
