- 2. The phase change from gas to liquid that occurs when a gas loses energy and its particles slow down and come together.
- 3. The phase change from solid to liquid that occurs when a substance absorbs energy and its particles move faster.
- 4. The ability to do work or cause change. Energy can cause matter to move or change state.
- 6. The phase change from solid directly to gas without passing through the liquid state. This occurs when a solid absorbs enough energy.
- 7. The amount of mass in a given volume of a substance. Calculated using the formula: Density = Mass รท Volume.
- 10. CHANGE A change in the size, shape, or state of matter without forming a new substance.
- 12. CHANGE A change that produces one or more new substances with different properties.
- 13. The phase change from liquid to solid that occurs when a substance loses energy and its particles slow down and lock into place.
- 14. PROPERTY A characteristic of matter that can be observed or measured without changing the substance into something new.
Down
- 1. The phase change from liquid to gas that occurs at the surface of a liquid when particles gain enough energy to escape into the air.
- 2. OF MASS LAW Matter cannot be created or destroyed in a chemical reaction. The total mass of the reactants equals the total mass of the products.
- 5. A state of matter with a definite volume but no definite shape. Particles in a liquid are close together but can slide past each other.
- 8. A state of matter with a definite shape and definite volume. Particles in a solid are tightly packed and vibrate in place.
- 9. Anything that has mass and takes up space. Matter is made up of tiny particles called atoms and molecules.
- 11. A state of matter with no definite shape and no definite volume. Particles in a gas are far apart and move freely in all directions.
- 12. PROPERTY A characteristic of matter that can only be observed when the substance changes into a different substance.
