- 7. The process where a gas transforms directly into a solid without first becoming a liquid.
- 10. To take away or eliminate a substance or quantity from a system.
- 11. The process of a solid becoming a liquid as it absorbs heat energy.
- 13. The smallest unit of an element, composed of protons, neutrons, and electrons.
- 15. The process where a gas turns into a liquid as it loses heat energy.

Down
- 1. The process of melting, where a solid becomes a liquid as it absorbs heat.
- 2. The transition of a substance from solid to gas without passing through the liquid phase.
- 3. A heterogeneous mixture where solid particles are dispersed in a liquid but can settle over time.
- 5. The process when a liquid turns into a gas at temperatures below its boiling point.
- 6. A measure of the average kinetic energy of particles in a substance, affecting its state.
- 8. The process of a liquid turning into a solid as it loses heat energy.
- 9. Combining ions or atoms to form new molecules or compounds.
- 12. The process of adding or removing electrons from an atom or molecule, resulting in a charged particle (ion).
- 14. Water vapour that is created when water boils and becomes a gas.
- 20. The force that holds atoms together in a molecule or compound.
- 21. A mixture of two or more metals, often created to enhance properties like strength or corrosion resistance.
