Matter, particles and properties

Matter is anything that has mass and takes up space

Matter is made up of elements, like fire, air and earth

There are [blank_start]three[blank_end] states of matter. [blank_start]Solids[blank_end] are the state with the lowest energy. The [blank_start]particles[blank_end] in a solid are fixed in place. Liquids have more energy, and the particles can flow over each other to take the shape of the container. Gases have the most [blank_start]energy[blank_end]. The particles are spread far apart, moving fast, and will move to take up as much space as possible.

Which of these are correct when talking about a solid, like a wooden block?

To change the state of some matter, you should add or remove heat energy

Material is the word used for a particular type of matter

All materials have the same properties

Matter can change [blank_start]state[blank_end] when you add or remove heat [blank_start]energy[blank_end] from it. Solids change into [blank_start]liquids[blank_end] by melting, while liquids change into [blank_start]solids[blank_end] by freezing or solidifying. Liquids change into gases by [blank_start]evaporating[blank_end], while gases change back into liquids by condensing. Though rare, solids can change directly into [blank_start]gases[blank_end] by sublimating. When they change back, it is reverse sublimation.
