The water vapour rises and comes out and if it is heated for a longer period the water comes out of the pot.
It doesn't, coffee is grown. The way a percolator works is by the change in the density of water when it is heated. Water is placed in the percolator then the riser tube is placed in and the filter cup with ground coffee in it is placed on the top of the tube, ABOVE the top surface of the water. The water is heated at the bottom of the pot, this hot water rises and is directed up the tube, cold water replaces it at the bottom of the pot, this cold water as the density is much higher forces the hot water up the tube where it overflows into the filter basket and percolates back down through the coffee grounds, then back to the pot to be cycled through again. The percolation slows down as the temperatures in the pot equalize, or the water level is lowered.
The heat transfer is by conduction.
It would be convection. When the water at the bottom of the pot is heated, its particles move faster, and they also move farther apart. As a result, the heated water becomes less dense. Recall, less dense water will float on top of a more dense one. The heated water rises the surrounding cooler water flows into its place. This flow created a circular motion called convection currents. (:
It doesn't, water turns into steam, or a gas when heated. Water turns into a solid when cooled

It will evporate... it will be water. Try it yourself!
Pot with water in it. Over a fire or on a wood heated stove.
Steam in a sauna Boiling stew in a pot.
convection currents an example is a heat radiator...it radiates heat which warms the air. the air rises as its heated and cooler air takes its place then being heated by the radiator...this continues until the room is heated and so is a pot is on a stove and the water is boiling and the cold water is at the top and it goes to the bottom
convection is when heat or energy enters water and goes through it. for example, when you are boiling water in a pot on a stove,the water at the bottom of the pot haets up first before the water on top because it's in closest contect with the heat,then that water at the bottom heats up and becomes light because hot thing are lighter then cold ones. the heated up water rises up to the top and the cold water which is heavy falls to the bottom and heats up aswell. this cerculation keeps going until the whole pot of water is heated. thereafter the pot of water boils.
It is made from clay found naturally. Heated up into the shape of a pot.
Liquids expand more than solids on heating
