| Question | Answer |
| What is an insulator? | A material or substance that does not allow heat or electricity to move through it easily. |
| The transfer of heat in a liquid (or gas) by the movement of particles, when less dense liquid rises and more dense liquid flows in to take its place. Radiation, Conduction or Convection? | Convection. |
| Wood, Gold, Plastic Porcelain, Fibre glass, Copper, Rubber Ceramic, Aluminium, Silver Which are the following conductors? | Gold, Copper, Aluminium, Silver |
| The difference between a conductor and an insulator? | Insulators allow limited particle movement as for conductors are able to have electricity move freely (electrons). |
| The transfer of heat or light as waves through space (or air). Radiation, Conduction or Convection? | Radiation. |
| True or False? Heat will continue to transfer until it is balanced. | True. |
| The transfer of heat depends on ____________ & ____________. | Temperature & Mass. |
| Series circuit or Parallel circuit? More than one electron path. | Series circuit. |
| What is conduction? | The transfer of heat from one particle to another, which occurs when the particles are very close together, as in solid. aka. method of heat transfer to another. |
| What is DC and define? | Direct current - flows one way. |
| Which colour absorbs the least heat, why? | Lighter colours absorbs the least heat because light is an energy which therefore, makes it reflective. |
| What type of energy can raise the temperature of an object? | Heat. |
| What is radiation? | Method of heat transfer which travels in waves. |
| Thermals are a result of? | Hot air rising (less dense air). |
