## Do you think that heat and light have mass Why?

Answer: No, heat and light do not have mass. They do not occupy space because these are not matter. Heat is energy in transit and light is a form of energy.

Is there mass of heat?

Heat doesn’t have mass but it contributes to the mass of matter by adding energy to it. The photons that carry heat energy gravitate and are affected by gravity, they do not have mass.

### Does energy have mass?

Energy does not have a mass. But mass is a form of energy. Rest mass of a particle is one form of energy. Relativistic mass of a particle is another form of energy which happens to be the kinetic energy of the particle.

How about smoke does it have mass?

Answer Expert Verified because smoke is made of soot, which is mostly fine particles of carbon mixed with air. since soot has mass (is made of matter), smoke has mass and it occupied space.

#### What is heat and light?

Heat and light are different but they are both forms of energy. Heat is a form of kinetic energy contained in the random motion of the particles of a material. Light is a form of electromagnetic energy. As with other forms of energy, heat energy can be transformed into light energy and vice versa.

How does light have no mass?

Light is composed of photons, which have no mass, so therefore light has no mass and can’t weigh anything. Because photons have energy — and, as Einstein taught us, energy is equal to the mass of a body, multiplied by the speed of light squared.

## Can light push objects?

Light carries momentum that can push on an object, but it can also move an object through thermal forces. Light can also exert force through the photophoretic effect, where preferential absorption of light on one side of an object leads to a temperature difference that causes the object to move.

How does heat increase mass?

The reason why hot objects are heavier is because E=mc^2. If you have absolutely identical objects that have the same weight exactly when they are at same temperature, then when one object is heated, it will weigh more. This is because the gravitational force depends on the stress energy tensor in general relativity.

### Does sound have mass?

Sound waves do carry mass. The calculations show that sound waves carry a tiny negative mass, which means that in the presence of a gravitational field, such as that of the Earth, their trajectory is bent upwards. Esposito and colleagues found that sound waves also generate a small gravitational field.
