The term 'turn to liquid' can be described by three different crossword solutions: DISSOLVE (8 letters), THAW (4 letters), and MELT (4 letters). DISSOLVE is a process in which a solid material is broken down into smaller particles and dispersed in a liquid. Thawing is the process of changing from a frozen state to a liquid state. Melting is the process of changing from a solid to a liquid state due to an increase in temperature. All three processes involve turning a solid into a liquid.
