The principal of the skinny tube is to allow expanded liquid to pass up it to indicate temperature
The bent tube Earth thermometer is a kind of a measurement that is used for measuring temperature of the earths crust.
The capillary tube of the thermometer ( in case of a mecury thermometer).
mercury
a thermometer--
If the thermometer was in a culture tube it would interfere with the subsequent transfers of culture to plates across the time intervals.
that depends on what type of thermometer. The tube thermometer, the kind with a glass tube with a red liquid in it, uses a small amount of mercury in a very small tube. When the mercury is heated, it expands, pushing further up the tube, as it cools it contracts, going down the tube. A dial thermometer also works on expansion and contraction, but with a coil instead of mercury.
A bore refers to the extremely fine or narrow tube found in a thermometer. It is called a narrow bore or a capillary.
The thermometer consists of a very fine glass tube having a very small bore and is called capillary tube. At one end of capillary tube a very thin glass bulb is provided. The bulb is filled with mercury( most of the times) or alcohol The other end of capillary tube is sealed. The capillary tube is protected by a thick glass tube called stem. On the stem are made markings. These markings are called graduations or degrees.
Galileo
The first thermometer was a tube filled with water and air.
either mercury or alcohol
Heat causes Mercury in the thermometer to expand, where as when it is cooled, it contracts.
