Mostly dark colors such as black, midnight/navy blue, etc
Bronze is a metal. All metals conduct heat.
red&yellow
This is because wood is neither a conductor of heat or coldness. In summer, the wooden benches don't conduct the heat of the sun and seem cool. And in winter, when it is very cold, it doesn't conduct the cold and seems warm.
It might be the energy saving bulbs.
When you look at a rock and see different colors, those colors are minerals .The pressure and heat causes the minerals in the rock to change into different minerals which cause the different colors in the rocks.
Light colors do not conduct heat better than dark colors. The color of an object affects how much heat it absorbs from sunlight, but once absorbed, the heat is conducted through the material regardless of color. Dark colors tend to absorb more heat from sunlight because they reflect less light, not because they conduct heat better.
nonmetals
no, metal is the best heat && energy conductor.
Electricity does not conduct heat. Your question is meaningless.
metals and air mainly
Light colors such as white and silver are the best at reflecting heat because they reflect most of the sunlight that hits them. Dark colors, like black, absorb more heat because they absorb most of the sunlight.
Silver is the best (and so fastest) metal to conduct heat.
The best conductor for heat and electricity is any type of metal element.
wax cookie sheets are usually best
can a teapot conduct heat
Dark colors such as black and dark green absorb heat the best because they absorb more light energy across the visible spectrum. Lighter colors such as white and light yellow reflect more light and heat, making them cooler to the touch.
Black is the best absorber of heat because it absorbs all colors in the visible light spectrum and converts them into heat.
