Q1: Change in volume of metals from absolute zero temperature to their melting points is

ANS:A - almost same for all metals.

The statement "almost same for all metals" regarding the change in volume of metals from absolute zero temperature to their melting points is not accurate. In reality, the change in volume of metals from absolute zero temperature to their melting points varies significantly for different metals. This variation is primarily due to differences in atomic structure, lattice arrangements, and bonding characteristics among different metals. Each metal has its own unique arrangement of atoms in its crystal lattice, and the strength of the atomic bonds within the lattice varies from metal to metal. As a result, the thermal expansion behavior of metals differs, leading to different volume changes as they are heated from absolute zero to their melting points. Metals with higher melting points typically have stronger atomic bonds and more closely packed crystal structures. These metals tend to exhibit less thermal expansion compared to metals with lower melting points, which may have weaker bonds and more open crystal structures. Therefore, the change in volume of metals from absolute zero to their melting points is not almost the same for all metals; it varies significantly based on the specific metal and its atomic characteristics.
