wrte any 5 application of thermal conductivity
Answers
Explanation:
Thermal conductivity refers to the amount/speed of heat transmitted through a material. Heat transfer occurs at a higher rate across materials of high thermal conductivity than those of low thermal conductivity. Materials of high thermal conductivity are widely used in heat sink applications and materials of low thermal conductivity are used as thermal insulation. Thermal conductivity of materials is temperature dependent. The reciprocal of thermal conductivity is called thermal resistivity. Metals with high thermal conductivity, e.g. copper, exhibit high electrical conductivity. The heat generated in high thermal conductivity materials is rapidly conducted away from the region of the weld. For metallic materials, the electrical and thermal conductivity correlate positively, i.e. materials with high electrical conductivity (low electrical resistance) exhibit high thermal conductivity.
- hope this helps to u

Answer:
Explanation:
Thermal conductivity is actually about the conduction of heat or transfer of heat.
Here are the some examples
1) A ice cube is melted in your hand because the heat from your hand transfer to the ice resulting in it's melting
2) Pouring of hot tea in a cup will make the cup of the also warm because of the heat transfer from tea to the cup.
3)Transfer of heat from iron to shirt while pressing is also a good example.
4) Transfer of heat during cooking to the food .
