What is not occupy space?

Air does not occupy any space.

Is air does not occupy space?

Matter is anything that has mass and volume. For example, air has mass and takes up space.

What does not have mass in the universe?

Photons, though they have no mass, exist in the universe, and where the universe is curved, they must follow.

What are the substances not considered as matter?

Everything that has mass and takes up space is matter. Every day, you encounter phenomena that either don’t have mass or don’t take up space. They are non-matter. Basically, any type of energy or any abstract concept is an example of something that is not matter.

Does mass occupy space?

Matter is anything that has mass and takes up space. Mass gives an object the property of weight and inertia (resistance to change in the motion of an object). The volume of an object is the amount of space it occupies.

Does not need any space to occupy?

Answer:Chair, air, love, smell, hate, almonds, thought, cold, cold drink, smell of perfume.

Which thing does not occupy space?

What is something that is not matter?

To answer the question, you need to understand what matter is. Everything that has mass and takes up space is matter. Every day, you encounter phenomena that either don’t have mass or don’t take up space. They are non-matter. Basically, any type of energy or any abstract concept is an example of something that is not matter.

Is there anything that has mass but does not occupy space?

Light has no Mass but it occupies space. Vacuum has no Mass but occupies space. Anything which has Mass and does not occupy space in my knowledge no things exist and if I say I have not read anything like that but still I want to complete this answer by telling you “Pain has Mass and it doesn’t occupy Space”…

Why do some particles have no mass and some have mass?

(Some particles have no mass. They don’t interact with the Higgs field; they don’t feel the field.) The quantity of interaction of these particles with other particles generate the mass,these particles have no interaction with elementary like particle photon, thus photon has no mass (although on the other hand photon has energy).

Does the same amount of matter exist before and after a change?

The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass. In a physical change, a substance’s physical properties may change, but its chemical makeup does not.
