This week in our chemistry science unit we are doing an experiment on why some liquids mix with others and some don’t. The thing we are going towards is changing one state to another.
Prediction/hypothesis: I predict that the water and milk will mix because they are the same viscosity and are made up of similar things. The oil wont mix with the water, i’m not sue why this occurs.
Aim: To observe what happens when we mix water and oil and water with milk. Find out why the outcomes happens.
Observation: Then we mixed the milk and water we observed that it was like a cloud spreading, after about 30 seconds you couldn’t tell he difference between plan milk and water mixed with milk. The oil and the water did mix.
Discussion/Explanation: When we added the milk to the water it just looked like milk, half of milk is water and the other half is fat so the water mixed in with the fat and just looked like milk. Then when we pour the oil into the water and found out that it is impossible or the two to mix because the oil molecule are more attached o each other than water molecule. It says on top because because it is less dense than water.
Conclusion: To sum up the milk mixes but the oil doesn’t simply because oil molecule are more attracted to each other than water molecule. Because milk is half fat if you apply heat it will Evaporate all the water and leave the fat behind. Then if you put more Heat the fat will burn.
