Explanation:
1) Fahrenheit is a temperature scale that bases the boiling point of water at 212 and the freezing point at 32. It was developed by Daniel Gabriel Fahrenheit, a German-born scientist who lived and worked primarily in the Netherlands.
2) Celsius, also called centigrade, scale based on 0° for the freezing point of water and 100° for the boiling point of water. Invented in 1742 by the Swedish astronomer Anders Celsius, it is sometimes called the centigrade scale because of the 100-degree interval between the defined points.
3) The kelvin is the base unit of temperature in the International System of Units, having the unit symbol K. It is named after the Belfast-born Glasgow University engineer and physicist William Thomson, 1st Baron Kelvin.
4) The lowest temperature that is theoretically possible, at which the motion of particles which constitutes heat would be minimal. It is zero on the Kelvin scale, equivalent to −273.15°C.
5) Kink plays an important role in thermometers. It prevents the rapid falling of the mercury back into the bulb of the thermometer. Hence we can measure the temperature of the body accurately and conveniently even if the thermometer is taken out from the body.
6) The heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
7) Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties.
