A:A liquid thermometer works by using the thermal expansion of a liquid within a capillary tube to measure temperature. The precision of this method varies by the liquid used, but all use the fact that when most liquids are heated, they expand. Common types of liquid thermometers use mercury, toluene or less toxic biodegradable liquids.

A:Thomas Edison was an early proponent of "hello" being used to answer telephones, but the man who invented the phone, Alexander Graham Bell, preferred the use of "ahoy" as a receptive greeting.
