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
The mass of an ingredient does not change during physical changes. Because a physical change does not make a new substance, the mass cannot change. For example, if you cut a sugar cube in two, then the sum of the masses of these two halves should be equal to the original mass of the uncut cube.
Yes, it does. It does not change in a Chemical Change though.
-------
In this case (physical change) mass doesn't change.
In a chemical change the total mass remain unchanged but the reactants are transformed.
no there isnt, mass is neither created nor destroyed...for example if u put sugar in water it dissolves and then u boil the water out and the sugar u had put in it is the only thing left
no, its always conserved .
Its never created nor destroyed.
No. Loss of mass is unique to the nuclear reaction.
chemical chemical
no.mass is neither created or destroyed
Some common characteristics of physical changes are change in texture, change in shape, and change in state. There can also be a change in temperature and a change in color, but these are also common characteristics of chemical changes. A physical change does not change the composition of the original substance.
This process involve chemical reactions but also physical changes.
The temperature remain constant during a change of phase.
It is a chemical change. A chemical change is when you can't take the item back to its original state. Ex. A baked cake can't go back to cake batter.
im think it is a physical change because there chemical bond are formed during ice makig.only a physical chage ocuur that the density of the water gets low and it becomes hard. regards Abdul karim
What changes and what remains the same during a physical change
During a physical change the chemical molecule is not affected; physical changes are changes of phase or form.
Yes. Chemical changes are irreversible, but physical changes can easily be changed back
During a chemical change the molecule is transformed; during a physical change the molecule is not transformed.
There are no chemical changes.
Physical. Physical changes include things such as changing shape or color. Chemical changes change the chemical properties of a material, often during a chemical reaction.
During a physical change, the matter of what the substance is made out of doesn't change.
Actually both physical and chemical changes are happening during cement mixing.

Physical. Melting is always a physical change.
During boiling of water,water changes its state from liquid to gas due to a change in temperature. Therefore it is a physical change.
The change in characteristics is entirely dependent on how you have physically changed it. However most physical changes effect shape and size.
