If it happens below normal room temperature, it's usually called "freezing". If it happens above room temperature, it's usually called "solidification".
Water reaches the point of freezing when it undergoes a phase transition from a liquid to a solid.
Mercury is the transition metal that is a liquid at room temperature.
Solid to liquid.
The process of a solid changing into a liquid is called melting. This occurs when the temperature of the solid reaches its melting point, causing the solid to transition into a liquid state.
The melting point is the temperature at which a solid substance changes into a liquid. When a solid substance is heated to its melting point, the particles within the solid gain enough energy to overcome the forces holding them in a fixed position, causing them to break free and transition into a liquid state.
The heat energy, or enthalpy, associated with a solid to liquid transition is the enthalpy of fusion and that associated with a solid to gas transition is the enthalpy of sublimation.
Solidification or Crystallization
All you have to do is freeze it.

Mercury is the transition metal that is a liquid at room temperature.
In physics, the solid to liquid process is known as melting. The three states of matter are solid, liquid, and gas. There is a change in phase or a phase transition in a substance when there is a change in either its temperature or pressure. The melting process is a phase transition.
Solid to liquid.
The phase transition from a liquid to a solid is called freezing or solidification.
Sublimation is the transition directly from solid to gas, without the intermediary liquid stage. The reverse (the transition directly from gas to solid) is called deposition or desublimation.
