Copper.
A2. Helium ii has a much greater thermal conductivity than copper - several hundred times.
Diamond also has a greater thermal conductivity and for this property is used as heat sink in some semi-conductor applications.

Can cold be transferred?
Yes because you are transferring heat
Transferring heat by direct contact is known as what?
Conduction
Witch method of transferring heat does not need particles?
Radiation does not need particles to transfer heat.
How does heat flow during heat transfer?
Heat flows through a substance when heat is provided to a substance, the molecules that receives it first gets excited and begins to vibrate to and fro thereby hitting another molecule and transferring this vibration to more molecules thereby transferring the heat energy.
What is the difference between a heat conducter and a heat insulater?
A heat conductor is something which is could at transferring heat. Think of a metal spoon in a pan of boiling water. The spoon feels hot because the metal is good at transferring the heat to your hand. On the other hand, an insulator is something which is bad at transferring heat. They can be used either to keep heat in, or to keep it out. For instance, because air is a good insulator, hot water tanks often are covered in foam, which traps air, which helps to keep the heat in.
How is convection produced?
convection is produced by the transferring of heat by the the flow of material.
What material will boil water the fastest?
The material that will boil water the fastest is metal. Metal is an excellent conductor of heat and will heat the water up quickly.
Which method of heat transfer is fastest conduction convection or radiation?
Conduction . . . depends on the properties of the material through which the heat is conductedConvection . . . depends on the physical movement of the material carrying the heat from level to levelRadiation . . . electromagnetic waves, moving from place to place at the speed of light.Looks like Radiation would transfer heat the fastest.
How are the processes of heating and freezing related?
They both have to do with the transfer of heat. Heating an object is transferring heat into the system. Freezing an object is transferring heat out of the system.
Which material will the Sun heat up fastest?
The darkest materialThe material with the largest area (100g of steel wool will heat up quicker than a 100g cube of solid steel)The material with the lowest specific heatThe coldest material (it is easier to heat from 0 to 10 degrees than from 20 to 30 degrees)The material that is isolated the best from it's surroundings
How is the aluminum bar transferring heat?
its a good conductor of heat
Which is the best way of transferring heat?
Radiation
A fire warms you by transferring what?
Heat energy
When the sun sets which material would cool down the fastest assuming they all have the same mass and initial temperature?
You would ALSO have to assume that the materials have the same shape.The material that cools down fastest would be the one that has the least specific heat capacity.
Which type of drive would offer the fastest performance time for the transferring of files?
SDRAM
Can cold be transferred?
Yes because you are transferring heat
Transferring heat by direct contact is known as what?
Conduction
