A:
(a) Temperature
Temperature: Temperature is a measure of how hot or cold something is, specifically, a measure of the average kinetic energy of the particles in an object, which is a type of energy associated with motion. Temperature is measured in degrees Celsius.
(b) Clinical thermometer
Clinical thermometer: A clinical thermometer cannot be used to measure high temperatures because it has been designed to measure only human body temperature which varies over a short range. If a clinical thermometer is used to measure high temperatures, it will get damaged.
(c) Celsius
Celsius: Celsius, also called centigrade, scale based on 0 0 Celsius for the freezing point of water and 100 0 for the boiling point of water.
(d) Radiation
It is the mode of transfer of heat in which heat is transferred through radiations. Example: sun etc.
(e) Conduction
Conduction: Those materials which allow heat to pass through them easily are called good conductors of heat. All the metals are good conductors of heat and electricity as well.
(f) Dark colour
Black colour absorbs all the wavelength of lights which are not reflected back to our eyes. it means black colour shirt or cloth absorbs all the light and convert this light into the form of energy (into the heat).
