One day Sally decided she wanted to make a ice cream. She took a bowl and filled it with ingredients creating a liquid.
I am freezing the particles to make a solid!
Sally then stirred all the ingredients together creating kinetic energy. She then put the bowl in the fridge to let the liquid freeze and turn to a solid.
After eating half the cone, Sally left the room leaving the remaining of the cone on the counter. When she got back it had melted because of the heat change in the air coming from the freezer. The heat left the particles moving faster than before, changing the state from a solid to a liquid.
Sally forgot about her ice cream and did not return to kitchen until the next day. To her surprise the ice cream had evaporated and turned into a gas. All that was left was the cone.
She became curious, and decided to investigate her fridge to see if any other phase changes happened around her. She noticed that in her freezer there was a thin layer of ice. She knew that this was deposition because the gas turned into a solid. When she checked her fridge she noticed the milk had water dripping down the sides and that this represented condensation.
Sally remembered, earlier that day in science class they played with dry ice. The teacher explained that the ice goes through sublimation, meaning the ice goes from a solid to a gas due to its extreme temperatures . Sally never realized that so many phase changes occur around her!
