Question

Application of thermal conductivity

Answer 1

Answer:

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.

Answer 2

$\huge\underline\mathfrak\green{Answer}$

⍟$\red{\text{Applications of thermal conductivity:}}$

⋙ Cooking materials are made up of metals but are provided with handles of bad conductor.

⋙ Thick walls are used in the construction of cold storage rooms. Brick is a bad conductor of heat so that it reduce the flow of heat from the surrounding to the room.

⋙ To prevent ice from melting it is wrapped in gunny bag. The gunny bag poor conductor of heat flow from outside to ice.
