What physical property could you use to separate sand and sugar? How would you do it?
Mix sand and sugar with water and heat the solution. the sugar dissolves and sand is left behind. filter and separate sand. Now heat the sugar solution, until water evaporates and sugar crystallises.
MELT THEM...DUHH!!!
The physical property that can be used to separate sand and sugar is their difference in solubility. Sugar is soluble in water, while sand is insoluble. Here's how you can separate them:
1. Add the sand and sugar mixture to a container of water.
2. Stir the mixture well to allow the sugar to dissolve.
3. Once the sugar has dissolved, the sand particles will remain as sediment at the bottom of the container.
4. Carefully pour the water, along with the dissolved sugar, into a separate container, leaving the sand behind.
5. If there is still some sugar remaining in the container with the sand, you can repeat steps 1-4 with fresh water to dissolve any residual sugar.
6. After separating the sugar-water solution, you can further isolate the sugar by evaporating the water. Leave the container with the sugar-water mixture undisturbed in a safe place.
7. As the water evaporates over time, the sugar crystals will start to form at the bottom of the container.
8. Once all the water has evaporated, you can collect the separated sugar crystals.
By utilizing the difference in solubility, you are able to separate the sand and sugar effectively.
