Grade 9 week 6

It is the heat transfer through a substance or from a substance to another by direct contact.

What are the examples of insulator inside the video presentation?

Give example of semiconductor

It is the transfer of heat through space in the form of waves.

One of the main ways of explaining differences in conduction. This uses the ‘band’ of material to explain a number of physical properties of conduction

It is made of a tungsten wire enclosed in a glass bulb from which air has been removed.

This is most obviously applied to sound studios, however, it can also be applied to regular buildings to prevent disturbances between rooms and properties.

It is define as the flow of energy from a warm object to a cooler object.

What is the melting point of tungsten as a filament?

It prevents the flow of energy between two objects.

What are the three ways in transferring heat?

It has a conductivity value between that of a conductor such as silver and an insulator, such as mica.

An electronic component that has mercury vapor in the glass tube which emits ultraviolet radiation when switched on.

The heat transfer in liquids and gases as particles circulate in currents. What kind of heat transfer is this?

A kind of insulation this can range from the coating of wire in household circuitry through to the insulation in capacitors in commercial and consumer goods.

this normally comes in It is a form of thermal insulation to regulate the heat flow between a building and the outside environment.

States that energy can neither be created nor destroyed but can be converted from one form of energy to another.
