because metal is a good conductor of energy (there are a lot of free electrons in a metal) and this will cause the metal to absorb and radiate more energy combined with the increased surface area of the heat sink

If a person had a metal plate in their head would a magnet stick to it?
no, the type of metal used is platinum which is unfavorable to metal or magnet.
What is the scientific term for heating metal and then rapidly cooling?
Annealing is a term used for when metal is heat hardened
What are Two strips of metal used to convert heat into electricity called?
water
What is the purpose of a heat sink in transistors?
Heat sinks are needed for transistors passing large currents. Waste heat is produced in transistors due to the current flowing through them. If you find that a transistor is becoming too hot to touch it certainly needs a heat sink! The heat sink helps to dissipate the heat by transferring it to the surrounding air. The rate of producing waste heat is called the thermal power, P. Usually the base current IB is too small to contribute much heat, so the thermal power is determined by the collector current IC and the voltage VCE across the transistor: P = IC × VCE The heat is not a problem if IC is small or if the transistor is used as a switch because when 'full on' VCE is almost zero. However, power transistors used in circuits such as an audio amplifier or a motor speed controller will be partly on most of the time and VCE may be about half the supply voltage. These power transistors will almost certainly need a heat sink to prevent them overheating. Power transistors usually have bolt holes for attaching heat sinks, but clip-on heat sinks are also available. Make sure you use the right type for your transistor. Many transistors have metal cases which are connected to one of their leads so it may be necessary to insulate the heat sink from the transistor. Insulating kits are available with a mica sheet and a plastic sleeve for the bolt. Heat-conducting paste can be used to improve heat flow from the transistor to the heat sink, this is especially important if an insulation kit is used.
What is the difference between arc welding and resistance welding?
in arc welding only heat is used to weld metal. but in resistance welding pressure will also be used along with heat.
What is used for heat dissipation in ICs?
heat sinks
What Metal would be used in computer circuits and necklaces?
Gold wire is used in processors, and silver oxides are used as thermal conductor between processors and heat sinks.
Which type of metal is the worst conductor?
The worst metal conductor of heat is very probable bismuth with a thermal conductivity of 7,97 W/m.K.-------------------------------------------------------------------------------------------Aluminum conducts heat brilliantly, which is why it is used for most heat sinks and cooling fins, along with copper, another brilliant conductor of heat.--------------------------------------------------------------
How does aluminum foil help the pain from a burn?
Aluminum is a commonly used metal for a heat sinks. I use it in circuit protection but never on people. It draws heat away by conduction. The more surface area the better.
Where do heat sink go?
Heat sinks increase the rate of heat loss from the source into the environment, i.e. usually air. The heat goes to the same place as it would without the heat sink, it just does it quicker. Some heat sinks may be enclosed in a liquid, which is used to transport the heat elsewhere where it cools down and then returns.
Which term can be used to explain why a gold plate would heat up faster than a glass plate?
Specific heat capacity
Which parts are used to keep the video card cool?
Passive heat sinks,Cooling fans and Shrouds
If a person had a metal plate in their head would a magnet stick to it?
no, the type of metal used is platinum which is unfavorable to metal or magnet.
What is used to heat glass beakers that have chemicals in them?
A hot plate.
Why is metal used to make pans?
Because metal is a good conductor of heat.
Why metal used to make pans?
Because metal is a good conductor of heat.
What a blow torch used for?
It can be used to solder metal together or heat metal up for some purpose.
