Ice is water, so if you heated it it would melt into liquid water before it could boil. The boiling point of water, of course, is 100 Celsius or 212 Fahrenheit (at sea level).
Temperature affects an ice cube by either melting it or freezing it. If the temperature is warmer than the ice cube's melting point, the ice will melt into water. If the temperature is colder than the ice cube's freezing point, the water will freeze and the ice cube will grow.
An ice cube will melt when it is above the freezing point of water. At this point the individual molecules have enough energy to vibrate more causing the ice cube to melt.
Water + confined square container + temperatures below freezing point = ice cube
A sea water ice cube would melt faster than a normal ice cube because sea water has a lower freezing point due to the presence of salt. This means that it would require less heat energy to melt the sea water ice cube compared to a normal ice cube.

It will melt! But you have to add enough energy to equal the latent heat as well as to bring the ice up to the freezing point, if it is in a freezer to start it will be at about -21degC.
The cordial ice cube will likely melt faster than the water ice cube due to the lower freezing point of the cordial. The presence of sugar in the cordial lowers its freezing point, causing it to melt more quickly at room temperature compared to plain water ice.
Freezing point of water
The alcohol will lower the freezing point of the water, causing the ice cube to melt faster than it would in water alone. The alcohol-water mixture will create a solution with a lower freezing point, leading to quicker melting of the ice cube.
a ice cube in alcohol would melt fastest because of the heating molecules contracting with the ice cube molecules
melting point
The ice cube remains in its shape in the freezer because the temperature inside the freezer is below the ice cube's melting point, preventing it from melting or changing shape. As long as the temperature stays below freezing, the ice cube will remain solid.
