2. Standard unit of frequency
3. rate of occurrence: The doctor has increased the frequency of his visits.
5. The effect, result, or consequence of being compressed.
7. The transfer of heat by the circulation or movement of the heated parts of a liquid or gas.
10. Insulating material, often glass or porcelain, in a unit form designed so as to support a charged conductor and electrically isolate it.
11. The degree of heat in a living body, normally about 98.6°F (37°C) in humans.
12. Sound like waves having a frequency below the audible range, that is, below about 16Hz
14. a ringing or similar sensation of sound in the ears.

1. An instrument for measuring temperature, often a sealed glass tube that contains a column of liquid, as mercury, that expands and contracts, or rises and falls, with temperature changes, the temperature being read where the top of the column coincides with a calibrated scale marked on the tube or its frame.
4. a sound heard again near its source after being reflected.
6. the act or process of making less dense or the state of being less dense
7. The transfer of heat between two parts of a stationary system, caused by a temperature difference between the parts.
8. A substance, body, or device that readily conducts heat, electricity, sound, etc.: Copper is a good conductor of electricity.
9. a unit used to express the intensity of a sound wave, equal to 20 times the common logarithm of the ratio of the pressure produced by the sound wave to a reference pressure, usually 0.0002 microbar.
13. The process in which energy is emitted as particles or waves.
