      Gallium melting point is 27.5 Celsius.
      Gallium freezing point is -19 Celsius.
      Dry ice temperate is around -78.5 Celsius,

      If you hold gallium in your hand it will melt, so you can see the nice transition as you hold in your hand from solid to liquid state of gallium.

      When you put dry ice on gallium you can see gallium freezing and converting into solid more like a crystal. With reference to the temperatures mentions you can see the fine transformation of gallium states.
