The only physical changes that have any effect on the mass
of an object are lopping a piece off or gluing a new piece on.
It is a physical change.

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. Mass is a measure of how much matter is in an object, and that does not change when the matter changes states. The matter will either contract or expand, depending on the current state and the state to be reached, but that does not change how much matter is in the object.
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.
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.
