Answer 2

• The major components of thermal properties are: Heat capacity. Thermal Expansion. Thermal conductivity.

• A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature. It ranges from -10˚C to 110˚C.

• Mercury

Mercury-in-glass thermometers have been considered the most accurate liquid-filled types. However, mercury is a toxic heavy metal, and mercury has only been used in clinical thermometers if protected from breakage of the tube.

• Precautions to be taken while using a clinical tehermometer

Thermometer should be washed before and after each use, preferably with an antiseptic solution

do not wash the thermometer with hot water

ensure that before use the mercury level is below 35°C.

Read the thermometer keeping the level of mercury along the line of sight.

Handle the thermometer with care, as you handle any glass articles

Don't hold the thermometer by the bulb while reading it.
