- 5.03 Phases of Matter ActivityPrepared For: Mrs. RousseauBy: John Merrill
- My name is John, and I want to introduce you to my friend, Mr. Glacier. He's solid and he's made out of frozen water.
- SOLID
- Hello, John here... I'm sorry to report that the sun (through Radiation) has melted my friend, Mr. Glacier. The temperature was higher than 0-degrees Celsius, and the ice turned him into a liquid when the temperature hit the melting point.His particles were packed tightly together, and then his particles started to separate as the melting started and he became a liquid.
- MELTING ~ RADIATION
- Here is my new friend, Mr. Lake. I miss Mr. Glacier, but Radiation and melting took him away from me.
- LIQUID
- Hi, it's John again! I have some more sad news. Just as Mr. Lake and I got to know each other, something terrible happened to him. The sun caused the temperature to rise (through Radiation) and caused the water to evaporate into the atmosphere. Evaporation is a type of vaporization that occurs at the surface of liquids and is a slower process than boiling. Here, the particles of a liquid slowly change to a gas, or water vapor.
- EVAPORATION ~ RADIATION
- As we add thermal energy, the particles expand, moving away from each other. They gain energy and move faster. This causes a change of phase from a solid to a liquid to a gas.I can't wait to meet my new friend, Mr. Vapor, but I might be waiting around for a while.
- GAS
