• There are 3 states of matter﻿
• Liquid﻿
• Gas﻿
• Solid﻿
• There are 5 properties of a solid: Definite shape and volume, Very incompressible, Particles have relatively little energy, Solid particles vibrate in place, Solids often have crystalline structures.
• The molecules in a square are tightly packed together, they have the least energy
• ﻿
• Solids﻿
• When energy is added to a solid it will turn into another form, For example; When heat is added to an ice cube it melts into water﻿
• Liquids are almost incompressible, they have fixed volume but they do not have a fixed or definite state, Liquids flow from higher to lower level, Liquids have their boiling points above room temperature, under normal conditions.﻿
• The molecules in a liquid are slightly less packed then the solid, they are further apart. When energy is added to a liquid it will change forms. For example; If water is boiled then it will evaporate into a gas.
• Some properties are;
• Liquids
• The molecules in gas are spread apart, they move and vibrate quickly
• Some properties of gas are; Low Density, Gases contain scatterd molecules that are dispersed across a given volume and are therefore less dense in their solid or liquid states, Indefinite Shape or Volume, Compressibility and Expandability, Diffusivity, Pressure.
• Gases
• Gay-Lussac's law states; "the pressure of a given amount of gas held at constant volume is directly proportional to the kelvin temperature. As the pressure goes up, the temperature also goes up and vice versa." Therefore, when the temperature, pressure, and the volume of gas all affect each other. This is important because the pressure and the temperature affect the constant.
• When energy is added to a gas it will change its form. For example; Condensation is when gas is turned into liquid
• Technically there are 5 states of matter; Solids, liquids, gases, plasmas, and Bose-Einstein condensates. But the main ones are Solids, liquids & gases.
• Everything consists of matter, Solids ﻿have the least amount of energy. The particles vibrate in one place, therefore they have low kinetic energy. __________________________________________________________________________________________________ Liquids have more energy becuase their particles can move more, consenquently, they have a higher kinetic energy level.
• ﻿Gases have the most energy. The particles move around constantly, they have the most kinetic energy.
