Since heat is a form of electromagnetic radiation, does it travel at the constant velocity of light?

dirtyd33 said:first of all vanadium you're wrong; heat is infrared, a type of electromagnetic radiation.
dirtyd33 said:I am operating on the premise that since emr travels constantly in vacuum and relative to any reference body, then vacuum's are present about and within every reference body. so on this ground any heat transfer is through vacuum, whether via conduction, convection, or radiation, and if it is indeed true that "it will disperse into its surroundings at varying speeds" (pauls1950), then that is emr traveling not at c relative to reference bodies. i can understand heat transferring at varied rates based on the qualities of the bodies involved, but for heat to move about bodies it must be moving through vacuum.
ZapperZ said:Your "operating premise" isn't universal, i.e. it is not the most general situation. You are focusing on ONE particular form of heat, which you should have clarified in the very beginning. Other forms of heat include the average kinetic energy of particles, which you would have come across in any lesson in thermodynamics. This isn't mediated as IR radiation but rather as the transfer of kinetic energy of particles.
If you dispute this, which is a standard definition in physics, then the impetus is on you to make exact references to support your claim.
Zz.
That's not true. From the dictionary:mate0 said:heat is specifically the energy contained in matter because its molecules are moving internally. radiation is not a form of heat, though it is a form of energy.
That applies to radiated heat.Physics. a nonmechanical energy transfer with reference to a temperature difference between a system and its surroundings or between two parts of the same system.
dirtyd33 said:Thank you spectracat for acknowledging/ reaffirming the universal concept of energy, in the presence of vacuums, that i was getting at.
dirtyd33 said:But this is what I am supposing, is that because absorbed infrared increases the same internal energy that is being increased via conduction that the two are roughly equivalent; that the increased internal energy of the particle is due to addition of photon masses, whether absorbed from radiation or conducted from direct contact of "macro" bodies. Zz, please don't get on my case about "overly speculative posts," I'm trying to conduct research and further my own understanding.
Yes, heat is a form of energy that is transferred from one object to another due to a difference in temperature.
No, heat and light are two different forms of energy and therefore have different velocities. Heat travels through conduction, convection, or radiation, while light travels through electromagnetic waves.
No, heat's velocity is not constant. It depends on the medium through which it is traveling and the temperature difference between the objects.
The speed of light is much faster than heat's velocity. The speed of light is approximately 299,792,458 meters per second, while heat's velocity can range from 0.00001 meters per second (in solids) to 300,000,000 meters per second (in gases).
No, heat cannot travel through a vacuum because it requires a medium (such as air or water) to transfer its energy. In a vacuum, there is no medium for heat to transfer through, so it cannot travel.
