They expand ------- No, normally metals expand when heated.
by heating, by applying electric field !!
Cold
The metal object would contract, i.e it would shrink.
Steel
The free electrons within the metal cause metal to conduct electricity because they drift easily with an applied electric force. All metal conducts electricity.
Heating the metal tool expands them. After fitting the wooden handles the tools are allowed to cool and, as they do so, they contract so that they grip the handles tightly.
The recycling of metals is the melting down of scrap metal, and reusing the melted metal to make something new, for example, taking an old car chassis, melting it down, then using the metal to cast a new chassis.

heat makes metal expand.
tips how to make notification letter not to renew contract
it moves Because almost all Elements expand when heated and contract when cooled. As you are welding the metal at that location is trying to expand because of the heat. Ahead of the weld area the metal isn't moving. Behind the weld area the metal is trying to contract as it cools. If the whole weld could be heated at once it would expand then contract at the same rate without distortion.
Yes, "contract" can be used as a verb to describe the act of making a formal agreement or reducing in size. For example, "They need to contract with the supplier for the new materials" or "The metal will contract as it cools."
