There is no gain in mass or matter in chemical or physical change for a couple of reasons. First, you can't gain matter. Matter cannot be made nor destroyed. Matter is anything that occupies space and weighs something. There is no gain in mass because because in the changes that may occur, you are not adding or subtracting any thing, but simply altering its appearance or the "kinds" of atoms.
During a physical change, the arrangement and structure of the particles are altered, but the actual particles themselves remain the same. Therefore, the total mass of the substance remains constant because no new particles are being created or destroyed.
The mass of something stays the same after a physical or chemical change because of the Law of Conservation of Mass. The law of conservation of mass states that matter cannot be created nor destroyed. Welcome :D
Actually the mass does change by exactly the amount that E = Mc**2 predicts. But in chemical reactions the change in mass is many orders of magnitude smaller than the accuracy of the best standard chemical balances. The change has been measured and verified on custom built ultraprecise balances, but such equipment is far beyond the budget of ordinary laboratories and unnecessary for their needs.
because, you cannot get rid of mass and if it is changing it's form it is just decreasing its density if it gets bigger, and increasing its density when it gets smaller
cause u have some mental problems haha...suckas..
When a physical action occur mass can be changed.
remain constant as no mass is lost or gained during a physical change like heating copper.
Mass is conserved during any change in color, volume, identity, or physical state. This principle, known as the law of conservation of mass, states that matter cannot be created or destroyed in a chemical reaction, only rearranged.
Neither of them affect mass in a closed system.
Most physical changes are reversible itβs part are just rearranged
In a chemical change, the total mass of the substances involved before and after the reaction remains constant according to the law of conservation of mass. However, the individual masses of the reactants and products may change due to the rearrangement of atoms in the chemical reaction.
Saying that mass is conserved during a physical change means that the total mass of the substances involved remains constant before and after the change. This principle is a fundamental aspect of the law of conservation of mass, which states that mass can neither be created nor destroyed in a chemical reaction or physical change, only transformed into different forms.

Physical changes are like cutting paper. The mass does not change. Chemical changes do not change total mass either. If you put a candle in a sealed container so that you may measure the total mass of the candle and the air before burning, then light the candle electrically but keep everything sealed, the total mass after burning will still be the same. But if you measure only the candle, then its mass has changed. So the mass of one single 'ingredient' will change during a chemical change.
it stays da same
Mass is neither a physical nor chemical change; however, it is a physical property of matter.
because some substances gain or loss weight during a reaction
In this case mass doesn't change.
A change in mass is not always an indicator of a chemical change because mass is conserved in chemical reactions. The total mass of the reactants is equal to the total mass of the products. However, there are some exceptions where a change in mass can occur due to the release or absorption of gases or changes in the physical state (such as evaporation or condensation) during a chemical reaction.
It is a physical change.
it is neither. no chemical reaction or physical change (melting boiling etc) can change net mass only nuclear reactions change the over all mass by converting mass to energy via Einstein's famous E=MC^2 equation
Temperature remains constant during the change in phase (physical state).
