Do all objects equally conduct absorb emit heat?

The emitting and absorbtion of heat is related to ' thermal radiation', whereas the 'conduction' of heat is a separate topic in physics. Firstly, thermal radiation is not equivalent across all substances. Darker coloured 'objects' such as those with a 'matt black' colour are the best emitters and absorbers of 'heat'. Lighter silvered 'objects' are the poorest emitters, the poorest absorbers, and the best reflectors of heat. Similarly, not all objects equally conduct heat. Metals are the best conductors of heat; and so non-metals are the worst. All Insulators do not conduct heat. Examples of good insulators are: plastic and wood.


What surfaces are better absorbers and emitters of thermal radiation?

Dark matt surfaces absorb heat radiation falling on them much better than bright glossy surfaces, such as gloss white or silver. They also emit much more heat radiation (at any given temp.)


Do All emitters transmit either a continuous wave or a pulsed waveform?

True


Which colours are the best emitters?

Colors with shorter wavelengths, such as violet and blue, are generally better emitters of light. This is due to the relationship between color and energy in the electromagnetic spectrum. Shorter wavelengths correspond to higher energy photons. Therefore, materials that emit violet or blue light often have higher energy levels, making them effective emitters. Keep in mind that specific materials and conditions can influence emission properties, so this is a generalization.


A material that conducts thermal energy well is a thermal?

Something that conducts thermal energy well is a thermal...conductor. If it does not conduct well it is called an insulator.

How does a cap-and-trade system work?

In a cap and trade system emitters are limited to the tonnage of pollutants they can emit. If they go higher they must pay for the excess emissions. Some emitters though are lower than the permitted emissions and can sell the "room" between their limits and their actual emissions to emitters who are over their limit. This is usually cheaper for the high emitters than the construction of treatment systems or paying thee government penalty.Many people feel this is not suitable system as it offers no incentive to the high pollution sites to improve.

In general good absorbers of electromagnetic radiation are also good?

Yes, Good absorber of heat are good emitters of heat. And in both the way rate is same. This is Kirchoff's Law.
