Copper is a good conductor, so it is used in electrical wiring.

Foam is a poor conductor, so hot cocoa in a foam cup will not burn your hand.

Lead is a very dense material, so it is used to make sinkers for fishing line.

Ice melts to liquid water at the melting point of water.

Liquid water boils and evaporates into gas at its boiling point.

Aluminum can be rolled or pounded into sheets to make rolls.

Tantalum is a ductile material, so it is used to make fine dental tools.

Salt dissolves in water.

• Carefully take the egg out of the water and set aside.

• Now, add 50 mL of salt to the water.

• Mix the solution thoroughly.– Which substance, the water or the

salt, is the solute? Solvent?
