WebIn this Doctoral Thesis, we investigated the physical properties of tin-containing alloys. Low melting point (505.06 K) and high boiling point (2876 K) make tin quite different from other elements, with the vast difference between the two temperatures. Generally, tin has low solubility with other elements, so it promotes phase segregation in ... WebCorrect option is A) Magnetization of iron is a physical change and not a chemical change as there is no change of state, no change of temperature, no smell and no evolution of gas. It is because: - no chemical process is involved. - After demagnetizing the iron it will lose its magnetic power.
