Objects that can radiate energy include stars, light bulbs, heated coils, and the Earth's surface. The type of radiation (such as heat, light, or electromagnetic waves) emitted by an object depends on its temperature and composition.
no...
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
Yes, all objects in the universe radiate some form of energy in the form of heat. This radiation is known as thermal radiation and occurs due to an object's temperature causing its atoms and molecules to emit electromagnetic radiation.
The total energy in all the particles of an object is the sum of their kinetic energy (energy of motion) and potential energy (stored energy due to position or state). This total energy is known as the internal energy of the object.
All bodies are subject to entropy, the constantly increasing disorder of the universe, all energy tends to thermal equilbirum thus, places of high energy/temperature/ pressure/ will radiate into places of lower energy/ temperature/ pressure. Also see wiki on blackbody radiation for more detail on that topic.
The average kinetic energy of all the molecules in an object is the temperature.
all living things use energy
its called internal energy.. temperature (defined as the degree of measure of heat, which is a form of energy) just helps you to compare the energies of two or more systems...
Yes planets do radiate noise. But not all of them do
Stars are not dormant. Which means sleeping. they are very active with atomic fusion, and radiate a lot of energy. Otherwise we wouldn't know of them. Eventually they may radiate all the energy they can, and will eventually shrink and collapse to a white dwarf or a brown star.
