WE KNOW THAT...

"When an object is heated then its inter-molecular distance increases."

{The inter-molecular distance of liquid is more than that of solid}

When metal is heated then the inter-molecular distance of metal increases and converts into molten metal and then this molten metal when cooled down then the inter-molecular distance decreases and then converts into solid.
