If air is considered as a poor conductor of heat why is it then you have to use insulator in handling hot materials?
When you pick up a hot item there is no air to insulate your hand.
What happens when heat hits a solid?
The same with when a light hits a solid; the energy either gets reflected or absorbed. If light hits a dark colored solid, most of the light will be absorbed, and the black object will get warm.If light hits a light-colored solid, most of the light will be reflected, and the white object will stay cool.By the way, the same thing happens to both heat and light, because heat is a form of light; heat is also called infrared light.Further answerIt does depend somewhat on what form this heat is in. If it's radiation then the answer above is fine. But if it's in the form of say, hot air, then there won't be any reflection, just conduction of the heat from the air to the solid.
What form of energy is the air?
Even though there is energy in almost anything, air is not usually considered to be a source or storage of energy.Anything solid, liquid, or gaseous has heat energy.Note: It is incorrect to say that air IS energy; rather, it HAS energy, in this case, heat energy.
When you turn on the heat in the car heat is being transferred by what?
I would say it is traveling by your cars air conditioner pump/fan with the air running across your heater core but since that's mechanics I'll tell you the physics answer too... Convection. Heat traveling through the air (or a liquid) to transfer to another (solid) material is called heating through convection. ;)
Why foam is used for insulation?
Foam can be a good insulator because it contains a lot of open gas spaces interrupted by fairly thin walls. The solid portions of the foam prevent much convection (air moving around carrying heat with it). Gas tends to be a lousy heat conductor, so all those air bubbles make the foam a poor conductor of heat - most of the conducted heat has to to travel through the limited solid structure of the foam (not much cross section for conduction).
What should be used to heat a solid in the presence of air?
a crucible with the lid slightly ajar :-)
Which solvent becomes solid when we heat?
air
Why is air required for cooking?
Air will let heat fully envelope a food item.
The process of heating an orc to a high temperature in the presence of air?
Heating an orc to a high temperature in the presence of air is a long process. It is when heat is transfer through atoms or molecules that move.
Is air an item?
no air is not a item
What is plate heat exchangers?
a plate heat exchanger is a metal plate which is will be in contact with another item eg air or another metal object to move heat from one to another
What condition is needed for a solid to change into gas?
For a solid to change into a gas, the conditions needed are high enough heat and low enough air pressure.
If air is considered as a poor conductor of heat why is it then you have to use insulator in handling hot materials?
When you pick up a hot item there is no air to insulate your hand.
How do the three types of heat transfer work together to to heat the troposphere?
three types of heat transfer work together to heat the troposphere by heating the solid with (conduction) air ( convection) and radiation from the sun.
How do the three types of heat transfer work together to heat the the troposphere?
three types of heat transfer work together to heat the troposphere by heating the solid with (conduction) air ( convection) and radiation from the sun.
How do the three types of heat transfer work together to heat the atmosphere?
Three types of heat transfer all work together to heat the troposphere by heating the solid with air and radiation which comes from the sun
