5.03 Phases of Matter ActivityMade by: Jenny mason
My name is Jenny, and I want to introduce you to my friend, Glacier. He's solid and he's made out of frozen water.
SOLID
Hello, Jenny here... I'm sorry to report that the sun (through Radiation) has melted my friend, 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, Lake. I miss Glacier, but Radiation and melting took him away from me.
LIQUID
Hi, it's Jenny again! I have some more sad news. Just as 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, Vapor, but I might be waiting around for a while.
