The hood of almost any vehicle will get hot when you have been driving the car and this is normal. Excess heat may mean the engine is running hot.
please dont say this question again
NO! Ideal materials for radiating heat are black. If a body is radiating lots of heat then its electromagnetic(EM) spectrum should peak below the visible range(Infrared region),making the material look dark.
green
This cycle is known as the greenhouse effect
Check the coolant level. Or, thermostat could be stuck in open position.
Dark surfaces are the best.
Clouds do not heat the earth though they can reduce heat radiating to space.
Heat promoting mechanism include exothermic reactions and the radiating of heat through conductance. Exothermic reactions include the combustion of carbon based fuels which release heat. The radiating of heat can come from electronic space heater that release warmth through their conducting metal filaments.
maybe you have air in your system, there should be a place where it can be bleed.
The cancer was caused by excessive nuclear radiation exposure. Some members of the military may have been exposed to high levels of radiation.
the color of light radiating that heat from it feels good
It moves mainly by radiating through gases.
