I failed Dr.Brooks science test. I do not understand phase changing.
Hear ye hear ye I am a genie I am here to grant all your wishes.
I am going to grant 4 wishes for you son.
Omg can you explain phase changing ?
Of course my dear, I am going to take you on a journey.
Liquid to gas
Look here son this is the process called evaporation. Evaporation is when a liquid changes forms to a gas. As you can see the gas is coming out the pot. The reason why the gas is coming out is because its heated. Now Im going to show you solid to liquid.
Billy is crying because he failed Dr.brooks test and a genie pops out of nowhere. The genie is here to grant all his wishes.
Solid to Liquid
Oh look son there is melting ice cubes on the ground. The reason it is melting because the temperature out side it is really hot out . The molecules attraction begins to get weaker. The molecules start to flow pass eachother. This process is called melting.
The genie is going to take Billy on a journey of phase changing.
Liquid to solid
why are we going to put it in the freezer ?
We are going to to put this in the freezer and wait an hour.
The water molecules attraction from liquid to gas gets weaker. As a liquid the molecules are loosely packed together and flow. As a gas the molecules start separate and move freely. The molecules fly around freely and collide with each other.
Liquid to solid
We are going to put this in the freezer because while its in the freezer the molecules are going to adjust to the temperature . The temperature Is decreasing. The molecules attraction starts to get stronger. The molecules movement is that they are vibrating in place.
The genie is explaining soild to liquid to Billy.
Its hot out here.
The genie is going to place the bottle of water In the freezer so it can freeze.
