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

Use a magnet to draw out the solid substance from the water.

Pass the solution through a filter to let the dissolved substance separate.

Boil the water away, leaving the substance behind in the beaker.

Pour the liquid along a rough surface that would catch the solid particles but not the water.

i need help plzz
