How it works
This state of matter worksheet shows a solid, a liquid and a gas as boxes of particles, with an arrow for each change between them. Six more containers ask which state they hold. Print it numbered, or answer on screen.

Tell the three states apart
In a solid the particles are packed in a regular pattern, so it keeps its own shape. In a liquid they stay close with no pattern, so it takes the shape of its container. In a gas they are far apart and fill the whole container.
Name the six changes
Melting and freezing run between solid and liquid, evaporation and condensation between liquid and gas, and sublimation and deposition straight between solid and gas. The two wide arrows show which way heat moves them.
- For a solid liquid gas worksheet for younger classes, ask only for the six containers in the bottom row.
- For a changing states of matter worksheet, cover the three boxes and ask only for the six arrows.
Questions and answers
Is there a states of matter worksheet PDF with answers?
Yes. Press Print this worksheet and choose Save as PDF in the print window. Print the answer key gives the numbered sheet with the name of every part listed under it.
Are states, forms and phases of matter the same thing?
In school science, yes. A forms of matter worksheet, a phases of matter worksheet and a solids liquids and gases worksheet all ask for the three on this page: solid, liquid and gas.
Which changes of state take in heat?
Melting, evaporation and sublimation take in heat. Freezing, condensation and deposition give heat out. On this changes in matter worksheet the two wide arrows stand for those two directions.
Can I use it as a states of matter quiz?
Yes. Press Quiz yourself on this worksheet. One part lights at a time and you pick its name: the three states and the heat arrows first, then the six changes, then the six containers.
