Liquids to Gases  **//The particles are fast moving and are widely spaced //****. They aren’t attracted to each other at all. **  **The particles now have so much energy that the forces of attraction are overcome//. The particles start to leave the surface of the liquid.// **  **Vaporization and there are two types of vaporization: boiling and vaporisatio ** **Liquids undergo the process of evaporation from changing from liquids to gases. ** **The theory of matter is that all matter consists of molecules. ** **The molecules in a bottled liquid are restricted in their motion by the walls of the container. ** **Liquids may become gases from being heated to the boiling point resulting in a change of volume which is called the transition. ** **When a liquid is heated its temperature rises until it reaches its boiling point. The temperature will then remain at that point until all of the liquid is boiled away. **  Gases to Liquids Condensation is the opposite of vaporisation because water vapour undergoes a state from gas back to liquid. But, a condition of saturation must exist before condensation can occur. That’s the air must contain all the water vapour it can hold before any of it can condense from the atmosphere. In the process of condensation the heat that was absorbed in evaporation by the water vapour into the air which is called the latent heat of condensation. As you might know condensation warms the surrounding air. When a gas is cooled its temperature will drop until it reaches the condensation point. Any additional cooling or heat loss will not lower the temperature until all of the gas is condescended into the liquid state. Then the temperature of the liquid will continue to drop as more cooling is applied. Once the liquid reaches the freezing point the temperature will remain at that point until all liquid is solidified. Then the temperature of the solid can continue to decrease**.** SOLIDS TO LIQUIDS Most solids cannot be turned into a liquid. Only solids with a boiling point can be turned in to liquids. EXAMPLE <span style="font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;"> <span style="font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;">Ice is a solid and if it melts it becomes water, which is a liquid. Another example would be ice-cream, if you boil it to its boiling point it melts and turns into a liquid. <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;">LIQUIDS TO SOLIDS <span style="font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;">Any solid that can be turned into a liquid can be reversed to be turned into a solid again. To turn into a solid it has to reach it;s freezing point. <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;">EXAMPLE <span style="font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;"> <span style="font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;">Melted ice cream could be reversed into non-melted normal ice cream. Water can again be frozen to make ice. <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;">LIQUIDS TO GASES <span style="font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;"> <span style="font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;">Liquids: particles begin to move freely but are attracted to each other <span style="font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;">Gases: particles now have so much energy that the forces of the attraction they go everywhere. <span style="font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;">The behaviour of the atoms in the liquid to the gases depends on the temperature of the liquid. <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;">LINKS: <span style="font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;"> [|www.bbc.co.uk/schools/scienceclips/ages/8_9/solid_liquids.shtml] <span style="font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;"> <span style="font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;"> [] <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;"> <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;"> <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;"> <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;">PICTURES <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;"> <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;"> <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;"> <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;"> <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;"> <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;"> <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;">Q & A <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;"> <span style="color: #ff0066; font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;">Q1. <span style="font-family: 'Candy Round BTN','sans-serif'; font-size: 14pt;">What is a solid?
