Does heat and light have mass?
Heat and light are both forms of energy, so yes. If you divide the energy by the speed of light in a vacuum squared (all in the appropriate units), you will obtain the value for the mass-equivalent of that energy.
Light has mass then why doesnt emc2 matter. The mass should become infinite and E infinite?
Okay....well that's why light does not have mass, or rather if it did, then it could not travel at the fundamental speed limit "c". This is a key to understanding the universe.
Does aluminum foil absorb heat?
People say it doesnt absorb heat because when the light points at the foil it bounces back.Also some people say it does absorb heat,but the heat cools down fast
What form of energy is in a candle?
The Light of a candle is part of the electromagnetic spectrum, so it is electromagnetic energy. It is also called radiant energy. A candle, however, can emit others kinds of energy like heat, light, sounds, kinetic energy (that makes the air move due to convection) and so on.
How heat is produced in nuclear reactor?
The nuclear fission results in mass loss (called mass defect) that transforms into energy according to the formula: E = mc2 (c is light velocity). This energy manifests itself as heat energy.
Heat and light have mass?
Yes ! Because the heat and light are occupying space and they are matter
Do heat and light have mass and occupies space?
No and no.
What type of chemical changes are involved in an atomic bomb explosion?
heat sound light and kinetic sorry if that doesnt answer your question but i tried :) ---- == == heat sound light and kinetic sorry if that doesnt answer your question but i tried :) ---- == ==

Is the moon made of plasmas?
no because the light that comes from the moon is from the sun. so it doesnt make its own heat or light. so no

Do light and heat have mass?
In so far as E = mc², yes For most practical, every day purposes though, we do not consider energy (such as light and heat) to have mass. If you weigh an object before and after heating it up, you won't be able to measure a change in its mass (unless the heat causes it to undergo some chemical reaction changing its composition). Note: We do know that light can exert pressure so it behaves like mass impacting an object. Generally the pressure exerted by light is too small to be detected under everyday circumstances but over long periods of time or from very intense sources it can be measured.
What caused the sun to give off heat and light?
The sun converts hydrogen into helium in the core of the sun. This neuclear reaction of four hydrogen atoms into one helium atom creates heat and light (kinetic energy) as result of the loss of mass (1 helium atom has less mass than 4 hydrogen atoms and the loss of mass is the heat and light)Plasma fusion
What are some examples of mass in science?
Light, heat, energy, emotions. All are massless.

Does the sun give us light?
the sun does give off light,heat,gravity,water cycle, mass, life,and vital vitamins
