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.
Which device has liquid in glass components?
thermometer
How does a glass thermometer works?
As the liquid in the thermometer is heated it expands, and the only way the expanding liquid can go is upward. As the liquid in the thermometer cools, it will contract, and the liquid will fall back down into the resevoir, causing the column of liquid to move downward.
Why does the expansion of glass in liquid-in - glass thermometer ignored?
For the basic principle, it can be ignored, since the liquid expands more than the glass.For exact calculations, the expansion of glass must also be taken into account. In practice, however, you'll want to calibrate the thermometer with known temperatures (for example, the temperatures of freezing and boiling water) - in which case such calculations are both unnecessary and useless.
