- 5. The temperature at which a given solid will melt.
- 6. Mass of a unit volume of a material substance.
- 8. A large body of air with generally uniform temperature and humidity.
- 9. The volume of a fixed mass of a gas at constant pressure varies directly with the Kelvin temperature.
- 10. The state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc.
- 11. The temperature at which its vapor pressure is equal to the pressure of the gas above it.
- 12. Quantitative measure of inertia, a fundamental property of all matter.
- 13. The degree of hotness or coldness of an object.
- 15. Describes a gas as a large number of submicroscopic particles (atoms or molecules), all of which are in constant, random motion.
Down
- 1. The amount of space that a substance or object occupies.
- 2. The constant value of the ratio between two proportional quantities.
