Insulation, use of a poor conductor of heat, dirt are some examples. You would need to be more specific if you have a particular question.
Heat insulation reduces the rate of heat flow. Sound insulation reduces the amplitude of the sound energy transmitted through a cavity.
Verticle down welding will always have lower penetration and less heat applied to the weld joint. As sheet metal is thinner and can not take excessive heat, verticle down reduces burn-through.
Power factor reduces overload capacity increased noise reduces
Not all modern houses have double glazing, though double gazing id a very commonplace practice. Double glazing significant reduces the rate at which heat penetrates the house reducing heating, and cooling costs.
A convection current is a natural flow or circulation of fluid due to a variation in its density due to temperature differences. As a fluid's temperature increases, its density reduces, and the fluid rises to be replaced by fluid at a lower temperature. Convection, together with conduction and radiation, is a method of heat transfer.
Heat insulation reduces the rate of heat flow. Sound insulation reduces the amplitude of the sound energy transmitted through a cavity.
Fur can hold a layer of air around it.That layer act as an insulator.So it reduces heat loss.
yes...heat reduces fat. Try going into the sauna!
It reduces heat as the silver foil reflects the heat back inside of the house.
It reduces the rate of transfer.
friction
An insulator
That would be - an insulator.
sterilization
The main idea is to reduce the heat transfer out of the vacuum bottle, or into it. A vacuum greatly reduces the transfer of heat by conduction and convection, while the mirror reduces heat transfer by radiation.
Its just because woolen clothes have fibres and between those fibres air is trapped which reduces heat loss. Air reduces heat loss because it is an insulator or poor conductor of heat.
