∙ 9y ago
Such thermometers are based on the fact that the liquid expands when the temperature increases. That's what the thermometers measure.

How does the thermometer used to measure air temperature differ from the thermometer used to take your temperature?
A thermometer used to measure air temperature uses a glass tube filled with a liquid either alcohol or mercury. When the temperature increases the particles of liquid expand, filling the glass tub. Thermometers that are used to measure you body temperature uses infrared sensors.
How are digital thermometers different from ordinary glass thermometers used to measure body temperature?

What characteristics must a liquid have before it can be used in a thermometer?
One thermometric property that is required is that it must vary linearly with temperature. In liquid-in-glass thermometers, the length of the liquid thread is often used to determine temperature. Thus when temperature increases, the liquid must expand uniformly with temperature, so that it can be used to measure temperature accurately.
Why liquid in glass thermometers are not suitable for industrial work?
Liquid in glass thermometers are fragile.For precise work, they need to be recalibrated frequently.
What is the definition of liquid filled glass thermometer?
a temperature-measurement device whose operation is based on the thermal expansion of a liquid. Liquid-filled thermometers provide a direct reading of the temperature.
Why are the thermometers called liquid in glass thermometers?
A so-called "glass" thermometer has a small bore-hole in the center of the glass that has some liquid in it. It's the activity of the liquid in the narrow hole that makes the thermometer a thermometer.
What metal element is used to make thermometers?
it is mercury. its actually a liquid at room temperature.
How did people measure the temperature in 1960?
They had thermometers that were a glass tube with mercury sealed inside. There were temperature markings on the outside of the tube that when the mercury reached that point it showed what the temperature was.
What thermometers are used in the medical field?
For similar reasons as any other field, to measure temperature. They are most often portable mercury or alcohol filled, sealed and graduated glass thermometers.
Temperature can be measured by what?
Temperature is measured by a liquid in glass thermometer in most cases. Other instruments such as thermocouples, resistance or digital thermometers are used for more extreme conditions.
What is the use of a liquid-in -glass thermometers?
1. has a high boiling point 2. good conductor of heat 3. does not wet glass does not vaporize easily 4. has a wide temperature range
What is a mercury filled glass tube that measures air temperature called?
All devices for measuring temperature are called thermometers. This includes those which use mercury and measure the temperature of the air.
