What metal made of radiator?

Radiators are made of a lot of metals with high melting points (example: Aluminum)


Example of a reflector with a rough surface?

A light colored or highly polished metallic surface will reflect a lot of heat (which is primarily infrared radiation). Some people in sunny places put a folding windshield screen up inside their car. The best ones have what looks like shiny aluminum foil on them to reflect the heat.


Why do Torches have shiny surface behind bulb?

To be more efficient! The flash bulb emits light in all directions, but you only use the light going in the forward direction, because the object you want to light up is in that direction. If there was no curved shiny surface behind the flash bulb all light that is emitted in a backward direction is absorbed by the camera, heating it up (quite a lot actually!), and going to waste. This is about half the light! The curved shiny surface acts as a mirror which reflects the backwards light back to the forward direction, thus more light is used in a useful manner. It is shiny because it needs to reflect light (mirrors are also shiny), and curved because it channels the light into a forward direction instead of simply reflecting it. You can actually see the same mechanism in car lights!


What are some practical applications for command strips?

Painter walls, glass items (Windows, glass tables etc), tiles, plaster Etc. are many surfaces you can stick the command strips to. Practical applications could be to use them to organize your house. You can use them hang items, such as pictures, decorations, mirrors or even your car keys!

Why dull black surface heats up more quickly than bright shiny surfaces?

The shinier the object, the more heat will reflect off of it. For example, a black carwill heat up much faster as the dull black will absorb the heat, while a shiny coloured car will reflect the heat molocules off.


What colour car absorbs more heat black red blue green whiteshinyb or dull surface?

Black cars tend to absorb more heat compared to cars of other colors because black surfaces absorb more sunlight and therefore heat up more. The surface finish, whether shiny or dull, does not significantly affect the heat absorption of a black car.


Why is water used as a coolant in car radiators?

Water is used as coolant in car radiators because it has high specific heat capacity of 4200 Joules. It has the highest specific heat capacity than any other substance. That is why it is used as coolant in car radiators


What is a car radiator made of?

most car radiators are copper or aluminum and plastic.


Why is water used in car radiators?

Water isn't used in car radiators, radiator fluid is. that is used because it is a liquid of the right density to hold radiated heat from the radiator and pass it around the car where it is needed.


Where can you buy the best car radiator?

A good source for car radiators is Radiators Online, a wholesaler that provides a wide range of choice amongst different Car Manufacturers. You could also try visiting your local mechanic.


Why has my car got two radiators?

I suspect one will be an intercooler for the turbo


How do a radiators low fan switch for a Toyota celica 2lt work?

The radiators low fan switch turns on when the a car is standing still. Radiators cool off using the air around the vehicle. When a car is parked or at a light the fans turn on at intervals to keep the engine cool.

It's a big black shiny car!


Why don't car radiators rust?

Most car radiators are made of aluminum or a combination of aluminum and plastic, which are not susceptible to rusting like iron or steel. Additionally, the cooling system in cars is filled with coolant that contains corrosion inhibitors to protect the radiator and other components from rusting. Regular maintenance, such as flushing and replacing the coolant, also helps prevent rusting.


What fluid do you put into car engine radiators along with anti freeze?

You mix it with water.


Why ethylene glycol is used in car radiators?

Because it has a good cooling co-effiency.
