The three states and heat 5

  1. Solid Particles packed tightly in a regular pattern. A solid keeps its own shape and its own volume.
  2. Liquid Particles close together with no regular pattern. A liquid keeps its volume and takes the shape of the container part it fills.
  3. Gas Particles far apart with no pattern. A gas takes both the shape and the volume of its container.
  4. Heat added Adding heat moves matter toward the gas. Melting, evaporation and sublimation all take in heat.
  5. Heat removed Removing heat moves matter toward the solid. Freezing, condensation and deposition all give out heat.

Changes of state 6

  1. Melting A solid turns into a liquid. Another name for melting is fusion.
  2. Freezing Liquid becomes solid. Water freezes to ice below 0 degrees Celsius, 32 degrees Fahrenheit.
  3. Evaporation A liquid turns into a gas. Scientists also call this change vaporization.
  4. Condensation A gas turns into a liquid. Water on the side of a cold drink is water vapor that condensed.
  5. Sublimation A solid turns straight into a gas. Dry ice, which is solid carbon dioxide, does this with no liquid stage.
  6. Deposition A gas turns straight into a solid. It is the reverse of sublimation.

Name the state 6

  1. Liquid The particles touch but have no pattern. They lie across the bottom of the beaker: a liquid.
  2. Gas The particles are far apart, all through the flask. That is a gas.
  3. Solid The particles sit in neat rows. The block keeps its own shape in the beaker: a solid.
  4. Gas A few particles spread through the whole beaker. Far apart and filling the container: a gas.
  5. Liquid The particles touch with no pattern and follow the round bottom. Taking the container's shape: a liquid.
  6. Solid A small block of particles in neat rows. It keeps its shape and does not spread: a solid.

How this list was compiled: How the particles of a solid, a liquid and a gas are arranged, and what each does in a container (a gas is well separated with no regular arrangement and takes its container's shape and volume; a liquid is close together with no regular arrangement and takes the shape of the part it fills; a solid is tightly packed, usually in a regular pattern, and retains a fixed volume and shape): Purdue University, General Chemistry Help, States of Matter, https://www.chem.purdue.edu/gchelp/atoms/states.html, read 2026-10-01; checked against NASA Glenn Research Center, Phases of Matter, https://www.grc.nasa.gov/www/k-12/airplane/state.html (a solid holds its shape; a liquid takes the shape of its container and has a fixed volume; a gas fills its container; water becomes ice below 0 degrees Celsius or 32 degrees Fahrenheit) and Wikipedia, State of matter, read 2026-10-01.

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.
