The liquid water changes state to become a , which into the . 6 cools lose outer water steam cannot moves 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 different food dye The different of water and used to separate them are their temperatures .
