You are worried that a solid substance has dissolved in a beaker of water in a lab. What would be a way to seperate the substance from the water?

One way to separate the dissolved substance from the water is through the process of evaporation. You can heat the solution in the beaker, causing the water to evaporate and leaving behind the solid substance. Once all the water has evaporated, you will be left with the solid substance in the beaker.
