Grade 8 science 3rd quarter module 1

• The particles are close together and vibrate rapidly.
• Examples of solids include rocks, metals, ice, wood, glass, and plastic.
• Solids have definite shapes and volumes that do not change unless the solid is deformed or melted.
• Liquid - A state of matter where particles move freely but remain close to one another due to intermolecular forces.
• Liquid molecules can slide past one another easily, allowing them to flow like water.
• In liquids, the particles are closer than those in gases but still move freely around one another.
• Liquid molecules can slide past each other easily, allowing them to flow like water.
• Liquids take on the shape of their container due to surface tension.
• Particles in liquids can slide past each other easily, allowing them to take on different shapes depending on their container.
• Examples of liquids include water, oil, blood, mercury, and alcohol.
• Gas - A state of matter where particles move very quickly and are far apart from each other with little attraction between them.
• Particles in liquids are closer than those in gases, but still far enough apart so they don't touch.
• Particles in a gas move very quickly and randomly, colliding frequently with each other and the walls of their container.
• The particles in gas are far apart from each other compared to solids and liquids.
• Gas - A state of matter with no fixed volume or shape, consisting of tiny particles moving rapidly at random directions.
• An example of a liquid is water.
