Density.

Gold has an extremely high density relative to the rest of the sand in the pan and will therefore fall to the bottom as one swirls the pan around. The water is there to provide a means by which to circulate the dirt mixture and eliminate the "sand" (the sand gets suspended in the water and spills over the sides of the pan as it is swirled).

And that's pretty much panning for gold.

What physical property can you used to separate the sugar from the mixture?

You can use the property of solubility in water to separate sugar from a mixture. Since sugar is soluble in water, you can dissolve the mixture in water and then use filtration or evaporation to separate the sugar from the other components.


What property of water makes things dissolve?

Water's polarity allows it to form hydrogen bonds with other polar molecules or ions, enabling it to surround and separate them. This process, called hydration, breaks apart the solute molecules and disperses them evenly throughout the water, resulting in dissolution.


Is solubility in water a chemical property?

Yes, solubility in water is a chemical property because it describes how a substance interacts with water at a molecular level. It is dependent on the chemical structure of the substance and involves the formation of new chemical bonds or interactions between the solute and solvent molecules.


When table salt dissolves in water is it a physical or chemical property?

It is both:It is a physical property because the solid salt becomes part of the liquid state of the water.It is a chemical property because the act of dissolving in water changes the salt (NaCl) into separate ions.

Which physical property can you use to separate sand and sugar?

Use water. Mix it around, the sugar will dissolve into the water. Use a siv to separate the water and the sand, put the water in a container and wait for the water to evaporate: leaving sugar and sand.
