He should carefully pick the larger pieces of glass . Then he should put the glass and copper sulfate crystals into a of . 2 dissolve sulfate some copper The will but the glass will not . He may be able to pour off some of the liquid into another beaker leaving of the pieces of glass behind . 3 fragments filtered filter paper basin mixture heated The of glass and blue liquid should be . The glass will be left in the . Marcus should be careful handling this .

Eventually some are able to overcome the weak that are holding them in place . The liquid water changes state to become a , which into the . 6 lose steam moves cannot cools outer water The in the condenser along the central tube . The condenser has an tube , through which water from the tap flows and this the condenser . The steam inside the condenser has heat energy transferred from it to the water in the outer tube . As the particles of water in the steam energy they move freely and condense into . 7 boiling properties dye food different The different of water and used to separate them are their temperatures .
