What are the different types of thermometer in science?
Three types of thermometers are alcohol, liquid crystal, and infrared radiation (pyrometer). The three main temperature scales are Celsius, Fahrenheit, and Kelvin. Temperatures can be converted from one scale to another using temperature conversion equations.
Does laboratory thermometer have kink?
Usually, the function of the kink in the thermometer is to break the flowing connection of mercury in the capillary and the bulb area at the lower end of thermometer. In laboratory thermometer, the temperature is measured continuously to note temperature change. … Therefore, a laboratory thermometer does not have a kink.

Which thermometer is best digital or mercury?
1. Digital thermometers provide faster results. Digital thermometers provide fast results as opposed to mercury thermometers whose readings are slower to realize because you have to wait for the mercury to heat and then slowly rise to display the temperature.
Why mercury is used in thermometer?
Mercury is the only one in liquid state at room temperature. It’s used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it’s used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.
Does laboratory thermometer have mercury?
Laboratory thermometers
A laboratory thermometer has a long stem with a silver bulb at the end. The silver color in the bulb usually means there is mercury in it. Mercury becomes bigger as the temperature becomes hotter. But mercury is a poison to humans.
