Topic 1-states of matter

• In a gas the particles have the most energy, as the particles are the most spread apart with a random arrangement

  
• In a liquid particles have more energy that those in a solid but less than those of a gas and the particles are closer together but have a random arrangement

  
• Solid has the least energy- particles are not moving are just vibrating and they are arranged regularly and very closely together

  
• Solid to a liquid is melting
• liquid to a solid is freezing
• liquid to gas is boiling
• gas to liquid is condensing
• Solid to a gas is sublimation
• Coloured solutions are diluted by adding water because the particles of the colour diffuse to the air of low concentration mixing with the water molecules causing dilution
• Solvent is the liquid in which the solute dissolves
• Solute is the substance that dissolves in a liquid to form a solution
• Solution is mixture formed when a solute has dissolved in a solvent
• Saturated solution is a solution in which no more solvent can be dissolve
