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.

∙ 11y agoThe 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

∙ 6y agoActually 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.

∙ 15y agobecause, 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

What is conserved during any change color volume identity or mass?
The answer is mass. The Law of Conservation of Mass states that when a chemical or physical change takes place, you end up with the same amount of mass that you started in. It may just be in a different state, such as a gas.
How does physical change and chemical change affect mass?
Neither of them affect mass in a closed system.
How is the physical change in the robot reversible and how can you tell that the change follows the law of conservation of mass?
Most physical changes are reversible it’s part are just rearranged
Is decompositon a chemical property?
A physical property is part of the make up of something that has a physical mass. No decomposing is not a physical property but rather both a physical change and a chemical change hence changing the chemical properties . The physical change is when the mass changes due to the brake down of the chemical and physical properties.
How does a chemical change affect mass?
The law of conservation of mass, states that mass is conserved in chemical reactions. chemistry is the study of the composition of matter, (what stuff is made of) ans the characteristic changes in the composition of matter. Such as what kind of "stuff" will burn, rust, rot, or otherwise change what it is made out of. If we add the weight (mass) or reactants such as paper and air before the fire and then take the mass (weight) after the fire of the smoke ans ashes, the mass is the same. ONLY in nuclear reactions is mass converted to energy, only in stars nuclear reactors , and atom bombs is mass (weight) converted to energy( light, or heat). So stars are losing mass (weight). A physical change is not a change in composition, typical physical changes are the melting of solids, and the boiling of liquids. Also cutting something big into little pieces, is a physical change NOT a chemical change a short board is still a board.
What does it mean to say that mass is conserved during a physical change?
There is one meaning when mass conserves during a physical change. This means that mass will stay the same after the change.
What property stays the same during physical change chemical change?
mass
What properties stay the same during physical and chemical change?
mass mass
Mass does not change during a chemical change how about for a physical change?
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.
What happens to mass during chemical and physical change?
it stays da same
Is mass a chemical change or physical change?
Mass is neither a physical nor chemical change; however, it is a physical property of matter.
Why is mass converted during a physical change?
because some substances gain or loss weight during a reaction
Does mass change in a physical change?
In this case mass doesn't change.
What is it called when there is no change in mass?
It is a physical change.
Why isn't a change in mass an indicator of chemical 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.
Does mass of ingredients change during a physical changes?
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
How does temperature change during change of physical change?
Temperature remains constant during the change in phase (physical state).
