General Chemistry information: Chemistry is and has been a long used subject in everyday life and scientific reasearch, chemistry is the combination or production and discovery of various chemicals and elements. (periodic table below) Chemistry has helped us in everyday life in many many ways such as new medicines, growth inhancers and many sprays and anti toxins to improve everyday life.

Definitions: Solid: A material or object thats insides are completely full and is measured in grams, kilograms and tonnes Liquid: An object or substance that is commonly measured in mL,L, and KL Gas: A form of substance that is made up of moleculiar mobility and an unknown exspansion Particle:One of the very small object made from matter or an atom and many other substances Compress: To press or push a object or substance together causing it to get smaller in size

Questions For Changing matter: 1.What is Sublimation? To heat up a solid and make it turn from a solid to gas instead of changing into liquid for example:Dry ice 2.Suppose you increased the pressure of the air above the boiling liquid.what would happen to the boiling point of the water? Because the liquid wants to turn into a gas becuase it is being heated and it has enough energy to but they are being pressured by the gas particles above them causing them to work faster and use more energy and that will make the temperature higher. 3.Imagine that you are trying to boil water for a cup of tea up a mountain. Why would the cup of tea tase horrible? Like question two the liquid particles in the tea will be pushed down by the air particles around a mountain and the liquid particles will work harder to try and become a gas causing more emergy to be applied and the tea will get hotter and when you drink it, it will burn your tongue. 4.Does water contract or expand on changing from a liquid to a solid? It contracts becuase the liquid particles are more spaced out adn solid particles are more closed causing it to close.
