It is a physical change.

mass
Neither a chemical nor a physical change results in a change in mass. According to the law of conservation of matter/mass, matter can neither be created nor destroyed. This law holds true for physical and chemical changes.
Mass over Volume+Density, so mass and volume.
In a physical change, the mass remains the same since it involves a rearrangement of particles without changing their identities. However, in a chemical change, the mass can change due to the formation or breaking of chemical bonds, resulting in a gain or loss of mass.
Mass is neither a physical nor chemical change; however, it is a physical property of matter.
In this case mass doesn't change.
It is a physical change.
No, a substance does not change mass when it changes physically. Physical changes, such as changes in state (solid, liquid, gas) or shape, do not affect the mass of the substance. The total mass remains the same before and after the physical change.
Mass is the measure of inertia and if you change the mass the inertia will change.
A change in temperature can change the rate of physical or chemical change.
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.
It is called a physical change.
No. A physical change like melting does not make something's mass change.
The physical change in a robot is reversible if the change does not alter the molecular structure of the materials involved. If the robot is disassembled and reassembled, the change is likely reversible. One can tell that the change follows the law of conservation of mass by weighing the robot before and after the change. If the mass remains the same, then mass has been conserved.
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.
