It is called a thermometer - used to measure temperature. The liquid in the bulb expands more than the glass when the temperature rises, so the length of the column of liquid in the tube increases with temperature.

If the last word was meant to be "alcohol", then the answer is a thermometer.

Thermometer. They contain Mercury which is a metal.

The red liquid in a thermometer is Mercury, which is usually encased in a glass tube

Mercury does not wet glass due to one of it's most significant properties. Mercury will not cling to the glass that contains it.

The sensor is just the mercury, a liquid metal.

They are made out of glass which is a metastable solid.

The liquid is usually mercury or an alcohol-based liquid. The liquid rises because its volume increases as it is heated more than the glass that surrounds it, and the only way the liquid can go as it expands is upward.

Yes, above the mercury or the other liquid.

Mercury conducts electricity. These switches are usually used in thermometers in air conditioners, etc. There is a coil that is temperature sensitive that causes the mercury to tilt. There are also two electric poles inside of the glass the mercury is contained in. If the glass it tilted in one direction, the liquid mercury encompasses both poles and completes the circuit. If the glass is tilted in the OTHER direction, the mercury moves away from the poles and opens the circuit.

Is a very heavy liquid and doesn't wet glass

The red liquid in a liquid-in-glass thermometer is mineral spirits or ethanol alcohol mixed with red dye. A grey or silver liquid inside the thermometer is mercury. Mercury thermometers are not used anymore due to the dangers associated with mercury.

There are many kinds of thermometer in use. Liquid in glass thermometers usually contain alcohol (dyed red or blue) or mercury (silvery coloured).

Mercury's precipitation refers to the wetting of a particular glass by mercury. The mercury in this form is usually easily removed from the glass by scrubbing.

Clinical thermometers. They can be (and usually made) by glass hollow rods with mercury inside). So I would say 'no diiference' considering the fact that: A clinical thermometer made with glass and mercury inside. Now - a - days other types of thermometers are used (to avoid mercury). Some contains alcohol (for glass type), some are made up like robbons with censors implanted.

For a classic thermometer: glass and mercury, colored ethanol or another liquid.

One common type of barometer contains a glass tube filled with mercury which is then inverted over a pool of mercury. The height of the column of mercury is the pressure that is placed on the pool of mercury. This is air pressure.

Glass is usually cooler than your breath. Breath contains moisture that condenses on the glass.

The "wetting" that happens when an object is immersed in a liquid depends on the surface energy of the object and the capilary forces in action on the surface of the liquid. for example mercury will not "wet" glass but water can wet the same glass.

a lab thermometer did not have a constriction as compared to clinical thermometer. it have a wide range of measurement and usually contains alcohol
