- 1. Quarter3: Module 1/Week 1-2 (S8MT-IIIa-b-8) MELC: Explain the properties of solids, liquids, and gases based on the particle nature of matter 8 SCIENCE
- 2. • Explain the particle nature of matter. Objectives: • Compare the properties of solids, liquids and gases in terms of arrangement and movement of particles. • Identify samples as matter based on its general/common properties.
- 3. ELEMENTS COMPOUNDS In Grade 7 you have learned how to classify materials such as mixtures, elements and compounds. All of these are matter. HOMOGENOUS MIXTURE HETEROGENOUS MIXTURE
- 4. ACTIVITY NO.1: Identifying Matter
- 5. HEAT is the energy being transferred between bodies from high to low. LIGHT is a form of energy that is visible to human eye. If Heat & Light are forms of energy, and energy is not a form of matter because it is not composed of atoms or molecules. Therefore, Heat & Light are not matter.
- 6. What is matter? Matter is anything that occupies space and has mass. NON-LIVING THINGS LIVING THINGS
- 7. Properties of Matter MASS is the amount of matter in an object. You can measure mass of an object by using a balance or a weighing scale. It is the property of matter that will not change under all conditions. are characteristics that describe the matter. double beam balance digital weighing scale analog weighing scale Matter can also occupy space. The measure of the space occupied by an object is called VOLUME.
- 8. All matter have mass and volume. There are other properties of matter such as: hardness, texture, color, flexibility, malleability, and electrical conductivity
- 9. STATES OF MATTER SOLID •Particles of solids are tightly packed. •They are vibrating about a fixed position. Solids have: • a definite shape • a definite volume. Heat
- 10. STATES OF MATTER LIQUID Particles of liquids are loosely packed but are far enough apart to slide over one another. Liquids have: an indefinite shape a definite volume. Heat
- 11. STATES OF MATTER GAS Particles of gases are very far apart. They move freely and have a lot of energy. Gases have: an indefinite shape an indefinite volume. Heat
- 12. What is matter made of? A particle is a word we use for a small piece of matter. Matter is made up of very small particles. Table Salt The particulate theory of matter describes what matter is made of.
- 13. Particulate Nature of Matter The particles are very small, invisible and cannot be seen with our naked eye. There are spaces between particles in matter. The spaces between particles are different in solids, liquids & gases. The particles of matter move at different speeds in solids, liquids and gases. The particles are in constant and in random motion. Solid Liquid Gas
- 14. The ancient Greek philosophers proposed ideas about what matter was made of. Almost 2,500 years ago, Leucippus and his disciple, Democritus believed that nature consisted of two things, “atoms and the void that surrounds them” (Knieram, 1995-2013). They believed that “atoms are physically, but not geometrically, indivisible.” For Democritus, atoms are indestructible and completely full, so there is no empty space. Both Leucippus and Democritus had the idea that there are many different kinds of atoms and each of them had specific shape and size and that all atoms move randomly around in space. However they did not give an explanation for the motion of atoms. (Knieram, 1995-2013).
- 15. Democritus believed that any piece of matter can be divided and subdivided into very small particles but that this process ended at some point when a piece is reached that could not be further divided. He called this particle, “atomos”, a Greek word which means indivisible particle. Democritus’ ideas about the atom were later challenged by other Greek philosophers, most strongly by Aristotle.
- 16. The idea of the atom was not further explored until a little over two centuries ago when John Dalton presented concrete evidence that all matter is made of very small particles called atoms. Today, we know that although atoms are very small, they are not indivisible as Democritus thought, rather they consist of still smaller particles,

There are spaces between particles in matter. The spaces between particles are different in solids, liquids & gases. The particles of matter move at different speeds in solids, liquids and gases. The particles are in constant and in random motion. An atom is the smallest particle of an element but it has its subatomic particles called neutron, electron and proton.

- 35. • Describe what happens to the molecules or atoms when matter absorbed or released heat energy. Objectives: • Determine the type of physical change that matter undergoes.
- 38. Direction: Identify the physical change in a substance’s state of matter and describe each phase change. 1. 2. 3. 4. 5. 6. Physical Change
- 39. Physical Change
- 40. Physical Properties Physical properties are used to identify, describe and classify matter. Characteristic of a substance that can be observed (using your senses) without changing the substance into something else.
- 41. Changes in Matter Change in state of matter is brought about by absorbing or releasing an amount of energy or heat. PHYSICAL CHANGE - when the composition of the substance is not altered in the process.
- 42. Physical Properties Size Shape Solubility Density Hardness & softness Volatility Conductivity Ductility Malleability Freezing point Boiling point Melting point Magnetism Viscosity
- 43. The physical change of solid to a liquid by the addition of energy as heat. 1.Melting
- 44. Melting point The temperatures at which the solid form of the element or compound is at equilibrium with the liquid form. Basically the range at which the solid changes its state into a liquid. The melting point of ice is zero degrees Celsius.
- 45. 2.Freezing The change in state in which a liquid becomes a solid as heat is removed.
- 46. Freezing point The temperature at which a liquid changes into a solid.
- 47. 3.Evaporation The change of a substance from liquid to gas. Volatile Liquids evaporates easily (acetone, perfume, benzene, hexane)
- 49. Boiling point The boiling point of an element or compound means the temperature at which the liquid form of an element or compound is at equilibrium with the gaseous form. The boiling point of water is 100 degrees Celsius.
