dissolving
Storyboard Tekst
- A mixture is a combination of two or more substances. Substances can be separated. Parts of a mixture are not joined together chemically, so each substance keeps its own properties and have the same properties as when they were mixed.

- hi sophie, today i'm going to tell you about Mixture
- what's that
- yes, such as evaporation and condensation. evaporation can seperate water with objects, for example water with salt. condensation can seperate things from gas to water, for example seperating water from sugar and you have both sugar and the water.
- mixture can be seperated using many ways. for example magnetism, magnetism can seperate metal things with non-metal things. for example seperating sand with iron fillings with magnetism the result will of course had iron fillings stick to the magnet. there are others too like filtration, seperating big things with smaller things. like seperating gravel with sand and seperating tea with tea leaves.

- are there other ways of seperating a mixture?
- the difference between condensation and evaporation is that condensation seperates water with object and you still get the water but evaporation evaporates the water and you don't get the water. but both seperates specific liquid with solid

- what are the difference between condensation and evaporation?
- I get it now
- correct! solvent is the minor component in a solution, dissolved in the solvent, like salt and sugar. Solubility is the measure of the amount of a solute that will dissolve in a solvent. The ability of one substance to dissolve inanother is called its solubility. It can be high or low.
- Sophie, there's something called Solutions, Solution is a special kind of mixture inwhich one substance is dissolved in another. there's also solute and solvent and we'll talk about solubility later. A solvent is the substance that takes in, or dissolves, the other substance. Usually there is more solvent than solute. Asolution does not have to be a liquid. The air you breathe, for example, is a solution made up of gases.
- Annie's Shop
- so the air I breathe is made of solutions from gases?
- There's also factories that affect solubility like temperature High temperature create faster process of dissolve and size Small molecules are soluble than large molecules. do you now understand about mixture, solutions and solubility?
- Annie's Shop
- YES!
