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.
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
car radiators used to be made of copper, copper doesnt rust. most radiators are now made from aluminum.aluminum also does no rust
Almost all car manufacturers have used cast iron radiators at one time or another, however most are now made of an aluminum alloy that can cool the water intake quickly.
Distilled water IS good for radiators. In fact, manufacturers recommend using nothing but distilled water to mix with antifreeze. Tap water contains minerals, which can promote corrosion. So tap water should be used in a cooling system only in case of an emergency.
You mix it with water.
Water is used in household radiators instead of oil because of high specific heat and high heat of vaporization. Water is also cheaper than oil.
Because it has a good cooling co-effiency.
antifreeze antifreeze a fifty fifty micture of water and antifrez is best
Eethylene Glycol
water takes longer to heat up and cool down than other liquids
Antifreeze is a substance such as glycol which is used to lower the freezing point of water, and is used as an additive in the radiators of motorcars.
Water and antifreeze mixture. The antifreeze has additives that help prevent corrosion.
