Across
- 2. below 32°F (0°C).
- 4. the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great.
- 7. firm and stable in shape; not liquid or fluid.
- 9. the conversion of a vapor or gas to a liquid.
- 10. a substance or matter in a state in which it will expand freely to fill the whole of a container, having no fixed shape (unlike a solid) and no fixed volume (unlike a liquid).
- 12. the process of turning from liquid into vapor.
Down
- 1. the energy an object has because of the movement of its molecules, and heat can be transferred from one object to another object.
- 3. a substance that flows freely but is of constant volume, having a consistency like that of water or oil.
- 5. is an ionized gas consisting of positive ions and free electrons in proportions resulting in more or less no overall electric charge, typically at low pressures (as in the upper atmosphere and in fluorescent lamps) or at very high temperatures (as in stars and nuclear fusion reactors).
- 6. the action or process of liquefying due to heat.
- 8. the action of bringing a liquid to the temperature at which it bubbles and turns to vapor.
- 11. a coherent, typically large body of matter with no definite shape.
