A student draws these models of a solid and a liquid. One limitation of these models is that they do not show—

• That particles in liquids have more energy than particles in solids

• How the particles of solids and liquids are structured differently

• Why solids do not take on the shape of their containers

• Why liquids take on the shape of their containers

Which of the following tools would work BEST to separate a mixture of sand and iron filings?

• Magnet

• Funnel

• Stove Top

• Paper Filter

A student performs an experiment to separate salt and water by boiling the water until it turns into a gas called water vapor. Afterward, all that is left is the salt. Which would be the best hypothesis for this experiment?

• I can turn water into a gas and melt the salt by boiling it.

• If I boil the water long enough, then all that will be left is salt.

• Salt cannot be turned into a liquid or a gas so I can separate it from water by adding heat.

• If I add enough heat energy to the mixture, the salt will dissolve into the water.
