Melting point:
Explanation:
- Melting point is the temperature at which the solid and liquid forms of a pure substance can exist at equilibrium.
- As heat is applied to a solid, its temperature will increase until it reached the melting point.
- Kelvin is the SI unit of the melting point of material. Lanthanum is a chemical element with the symbol La in the periodic table & having melting point is 920 °C.
- Yttrium is a chemical element with the symbol Y in the periodic table & having melting point is 1,526 °C.
- Scandium is a chemical element with the symbol Sc in the periodic table & having melting point is 1,541 °C.
- Hence the increasing order of elements according to the melting power is as follows:
LA < Y < Sc
