| Heat energy is... | ... radiated from the surface of an object |
| The bigger the surface area... | ... the more infrared waves can be absorbed or emitted from the surface (a quicker transfer of heat) |
| Objects made from good conductors... | ... transfer heat more quickly than insulating materials |
| Why would a flask be double walled with a vacuum? | It stops all conduction and convection through the sides |
| Why would the walls on the inside of the vacuum be sliver? | to keep heat loss by radiation to a minimum |
| Why would the flask be supported by insulating foam? | To minimize the heat conduction to or from the outer glass bottle |
| Why would the stopper be made out of plastic? | To reduce any heat conduction through it |
