Become Liquid is a process that can be achieved in several ways. Thawing, melting, and liquefying are all methods of transforming a solid into a liquid. Thawing involves the gradual warming of a frozen material, while melting is the process of heating a solid until it reaches its melting point and turns into a liquid. Liquefying is the process of changing a gas or solid into a liquid by applying pressure or cooling. All three processes result in a liquid form of the original material.
