Classification of Matter
Solid - Has fixed shape and volume and cannot be compressed.
Liquid - Do not have fixed shapes, fixed volume, and cannot be compressed.
Gas - do not have fixed shape and volume, and compressible.
Melting - A process where solid turns to liquid.
Vaporization- Conversion of liquid to gas.
Sublimation - Conversion of solid to liquid.
Freezing - A process where liquid changes to solid phase.
Deposition - The laying down of sediment carried by wind, flowing water, the sea or ice.
Condensation- Conversion of gas to liquid.
Filtration - A process in which the solid particles are separated
Evaporation to Dryness - A process in which the soluble solid is heated up for the water to be evaporated..
Distillation - It is a process where a pure liquid is being separated from the solution
Chromatography - A method of separating two or more components that dissolve in the same solvent.
Mass - The amount of matter in an object.
Volume - the amount of space occupied by an object.
Temperature - the measure of hotness or coldness of matter.
Apparatus for measuring
Beaker - Used to hold liquids or solid samples.
Pure Substance - A form of matter that has definite composition and distinct properties.
Mixture - Combination of two or more substances in which the substances retain their distinct identities.
Elements - A substance that cannot be broken down into simpler form. It is composed of atoms that have the same atomic number.
Compounds - Composed of two or more elements combined with fixed proportions.
Heterogenous - Irregular Composition
Homogenous - Uniform Composition
Triple Beam Balance - Used to measure mass precisely.
Evaporating Dish - Used for evaporation process.
Graduated Cylinder - Used to measure the volumes of liquid
Erlenmeyer Flask - Used for mixing and heating liquids. Also used for other liquid processes.
Matter is anything that occupies space and has mass. It is made up of particles that cannot be seen by the naked eye.
