Applications of conduction:- 1) Bad conductor of heat is used as insulators. E.g. glass , thermo Cole , sawdust etc. 2) The calorimeters are kept in wooden box. 3) The coils of heavy duty transformers are kept in oil to protect it from excessive heat. 4) Thermos flax contain double walled glass vessel with vacuum to maintain the constant temperature. 5) Flame of Safety lamps is covered with good conducting material. 6) Thermal insulator is used to prevent heat loss to the environment.
Applications of radiation:-
1. White or light coloured are preferred in summer.
2. Heat radiators in car, machines are painted black.
3. Aeroplanes and ships are painted white.
4. High absorbing power of water vapour is a natural gift.
5. The polished surface of space craft reflect most of the heat radiated from sun.
6. Base of the cooking utensils is made black.
7. Inactivation of HIV by application of heat radiations.
8. Teapots has bright shining surface.
