Do all things radiate?
Yes, all objects radiate some heat BUT the hotter the object, the more heat it radiates!! radiation its self is not hot but when it is absorbed by an object its particles in the object move more rapidly thus heating it
What is the best material for conducting and radiating heat?
Silver is about the best for conduction, with copper not far behind. For radiation, a black body is best, and will radiate more heat the hotter it is. The sun for instance acts as a black body with temperature about 6000 deg C.
Why black colour absorb and radiate more heat?
The objects is black when no light reflect from it, hence, it absorb light very well. And at the same time, what can absorb light very well would radiate heat very well .
Does cold radiate from Neptune?
No. Cold cannot radiate, only heat can. This is because cold is not a thing unto itself but is simply the relative absence of heat. While it is very cold, Neptune actually radiates more heat than it receives from the sun. If it were not for this it would be even colder.
What is the definition of the word 'radiate'?
The definition of 'radiate' is to emit energy in the form of waves or rays. More specifically, 'radiate' also refers to energy being released in heat, gas or light form. Synonyms of the word include 'beam' and 'emit'.
Does black ink radiate heat more quickly then white paper?
Yes black ink radiates more heat than white paper. This is because more heat is absorbed by black ink more than white paper and it is required to radiates more heat due to its heat capacity
What planet delivers more heat then it gets?
All of the gas giants (Jupiter, Saturn, Uranus and Neptune) radiate more heat than they receive.
What kind of energy do you have when your in a black shirt and start to sweat?
Heat - generated by your metabolism. The colour of your clothes is not important save that a black shirt will radiate heat from you more easily than a white one, but will absorb more external heat such as from the Sun.
Do dark rocks absorb more heat than light rocks?
Dark rocks will absorb more radiant heat than light rocks, for the same reason that any dark object absorbs more heat than an equivalent light object. Light objects appear "light" to us because they reflect more light than objects which appear dark. Dark objects appear dark because they absorb more light and reflect less. However, dark objects will radiate more heat that light objects. Actually, dark rocks do NOT absorb more radiant heat than light rocks. Nor do they radiate more heat than light rocks. Dark rocks DO absorb more LIGHT than light rocks and they then radiate this light at heat. Light rocks reflect the light rather than absorb it and therefore do not radiate as much heat. If you put a light rock and a dark rock next to a HEAT source, the amount of heat absorbed will be related to the makeup of the material rather than to the color.
Does Neptune radiate less heat than it the receives from the sun?
Neptune radiates MORE heat that it receives from the Sun - the reason is still unknown. Possible reasons are atmospheric interaction or magnetic waves.
Which one is cooler a city or a forest during a hot summer day?
The forest is cooler. More shade and no concrete or blacktop to absorb and radiate the heat.
Why co2 absorbs more heat?
CO2 absorb more heat than other gases or we can say that the other gases are not able to absorb lower radition of infrared rays of 5 to 15 microns but CO2 absorb these and CO2 later on re-radiate these as longer rays ( as heat).
