Here is what we found out about the changes between solids, liquids and gasses.

LIQUIDS TO GASSES By Ben, Braydon and Kaleb Liquids to Gases The change between solids and gases is the temperature and the way the particles move. The boiling point of water is 100˚C. What happens is that the particles in the liquid move around quicker with the heat and rise into the air, which is called boiling. Gases to Liquids To change back to a liquid from a gas the gases have to cool, which is called condensation. This changes the particles from moving really fast to a controlled speed. Solids to Liquids By Georgia, Shannon and Emma //__ Melting  __// When a solid is heated, its temperature rises until it reaches its melting point. Any more heat added to the material will not raise the temperature until all of the material is melted. If you heat some ice, its temperature will rise until it reaches 0° C. Then the ice will stay at that temperature until all the ice has melted. The heat energy is used to melt the ice and not to raise the temperature. After the ice is melted, the temperature of the water will continue to rise as more heat is added. //__ Boiling  __// When a liquid is heated, its temperature rises until it reaches its boiling point. The temperature will then remain at that point until all of the liquid is boiled away. For example, the temperature of a pot of water will increase until it reaches 100° C. It will stay there until all the water is boiled away. The temperature of the steam can then be increased. //__ Cooling  __// When a gas is cooled, its temperature will drop until it reaches the condensation point. Any added cooling or heat loss will not lower the temperature until all of the gas is condensed into the liquid state.
