Question

metal ___ on cooling​

Answer 1

ganrally contract

Explanation:

the expansion or contracting of any material is due to the kinetic energy of its own atoms.

Answer 2

• A solid is formed by cooling molten metal. After that, the solid metal is mechanically molded into the desired shape.
• Because heat and plastic deformation may have a significant impact on a metal's mechanical characteristics, how these stages are performed is critical.
• The surface wear and abrasion resistance of metals are determined by their hardness.
• Hardness and ductility are both factors that influence a material's capacity to withstand denting from impact.
