Like the Sun, all the stars are radiating heat all the time. They lose the heat (or thermal energy) through radiation.

If a red star and a white star radiate energy at the same rate can they be the same size If not which must be the largest Why?
They cannot be the same size. The red star must be larger. Red stars are cooler that blue stars and so radiate less energy for a given amount of surface area. In order to radiate the same amount of energy as a blue star, the red star must therefore have a larger surface area.
Source of heat and light energy produced by stars?
Nuclear fusion
Does the sun radiate both visible energy and invisible energy?
yes.
Does the sun radiate visible and invisible energy?
Yes.
What is the relationship between color and temperature of the star?
It depends on the stars wave-lengths for most of it. Stars that are cool (for stars at least- measured in kelvin) normally radiate there energy in the electromagnetic spectrum as red. Even though all stars in the sky appear to be white. Hot stars radiate much larger wave lengths, causing an almost blue color to be emitted. The only way for us to know how hot a star is... is finding where it's wavelengths are at there "peek". Wave lengths are NOT visible to the human eye.
Do hotter stars radiate more energy at higher frequencies?
yes, they do!
How does water absorb and radiate heat energy?
ask someone esle i don't know
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'.
How come stars are so dormant?
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.
How did solar energy develop as a source of energy?
it become heat and radiate like a nuclear plant produce alot of of energy while your at it
What form of energy in energy of house lights?
House lights radiate energy as electromagnetic waves in the wavelength bands of heat and visible light.

Why do you think you become warm after a workout?
The body uses energy to work out; energy ends up as heat. If you cannot radiate or otherwise lose the extra heat, you become warm.
What objects can radiate energy?
All objects radiate energy at a rate depending on their temperature.
Does heat radiate through glass?
Yes, heat can radiate through any kind of physical matter if it has been there long enough - heat can radiate through concrete, it just takes a while.
Which method of heat transfer can take place if two objects at different temperatures are placed without touching each other in a vacuum?
Heat doesn't travel through a vacuum. The energy could be changed to light and radiate across the gap, so that would be radiation.
What causes stars to change during the white and black dwarf phases?
A white dwarf no longer produces energy through fusion but remains hot from the residual heat of the star it once was. It will radiate that energy away and slowly cool as a result, eventually becoming a black dwarf.
