Answer 2

Heat radiators in cars are coated with black color because black color attracts and absorbs a lot of heat.

Detailed answer

We all know that black is a great absorber of heat and we know that a good and working radiator requires all the heat from the engine to be absorbed and released outside.

• This is why it is advised to wear white clothes in the summer as black clothes absorb a lot of heat.
• Painting the radiator in black color helps to dissipate the heat much more quickly.
• This helps to cool the engine much more quickly than any other color.
