despite giving heat ,heat does not spre
Answers
Answer:
heat does not spread from one end to the other insulators
Answer:
HOPE IT WILL HELP YOU.
Explanation:
Heat is transferred through conduction and convection.
In conduction, heat will transfer from an area of greater kinetic energy to an area of lower kinetic energy.
Convection is the transfer of heat due to the bulk movement of molecules within fluids.
If heat does not spread from one end to the other, then the substance is poor conductor of heat.
Materials that are poor conductors of heat are called insulators.
They are used in switches, handles of utensils, etc.
Examples: Glass, Rubber, Wood
The given system is an example of an isolated system having a non conducting medium. In this case, he is neither transfered to other end due to conduction and nor to surroudning due to convection.
Non conductors do not allow the transfer of energy, rather they oppose the flow of heat energy from one end to the other. Actually there is no movement of molecues in them that would carry heat from one point to other
