MYP Physics Heat Transfer Questionbank

The latent heat of the substance

The luminosity of the emitting surface

The level of insulation efficiency

The length or thickness of the material through which heat travels

It proves that all insulators are actually good conductors

It suggests that diamond is a metal under high temperature conditions

It demonstrates that the link between electrical and thermal conductivity does not reliably apply to non-metals

It shows that free electrons are the only way to conduct heat

To increase the rate of conduction through the air

To increase the rate of convection by moving fluid particles

To increase the rate of radiation from the components

To eliminate the need for thermal insulation

The cooling of the fluid at a distance from the source

The sinking of cool, dense fluid

The bulk movement of the fluid from one region to another

The heating of the fluid at the source

The density must remain constant while the mass increases

The density must decrease so the fluid can sink

The density must decrease so the fluid can rise

The density must increase so the fluid can rise
