Wow! *pants* That was quite a work out! I really need some water right now!
Aw, I just realized there's no water left! I have no time to go to the grocery store!
Only ice in the freezer... I guess I can let it melt.
Since an ice cube is a solid, it's particles are closely packed but can't move around freely. So, the molecules vibrate, and the shape and volume of a solid are definite.
When thermal energy is added, the ice cube will melt into water. The particles in a liquid are able to flow and move around.
Even though the particles are free to move around, liquids have a definite volume, but an indefinite shape.
That was nice of Rose to teach me a bit about solids and liquids, that was pretty interesting.
Maybe I should call Tina back now.
An hour later...
Where's my water?
ROSE!! Did you drink my water?
What do you mean??
Hey, it wasn't me! The water probably evaporated.
Heat was added to the water, making it a gas. Gas changes its shape and volume to fill a container.
A gases shape and volume are indefinite. So, the water must have evaporated.
I'm back from grocery shopping, girls! Look at all this water I got!
