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.


Does light contains heat?

Light itself does not contain heat. Heat is a form of energy that is associated with the motion of particles in a material. Light, on the other hand, is a form of electromagnetic radiation that does not have mass and does not create heat on its own. However, when light is absorbed by an object, it can be converted into heat energy.


Do heat and light can occupy space?

No, heat and light are forms of energy, not physical matter, so they do not occupy space in the way that physical objects do. They can be present in a space, but they do not have a fixed volume or mass like matter does.


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.


Light has mass then why doesnt emc2 matter. The mass should become infinite and E infinite?

In the equation E=mc^2, the "m" refers to the rest mass of an object, which remains constant. As an object's speed approaches the speed of light, its relativistic mass increases, but this does not lead to infinite mass or energy. Instead, the equation shows that as an object accelerates, the energy required to further accelerate it increases.

Why is fire not considered to be matter?

Fire is not considered matter because it is a product of a chemical reaction that releases energy in the form of heat and light. Fire is a process, not a substance, so it does not have mass or take up space like traditional forms of matter.


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.
