How does a thermal expansion thermometer work
WebLiquid-in- glass thermometers measure the thermal expansion of a liquid, which is placed in a solid container, on a length scale. The mercury thermometer is one example of liquid thermometers. Alcohol is also used with this type of instrument. The temperature range is −80 to +330 °C depending on the liquid.
