What is the boiling point of ice?

The boiling point of ice is not very meaningful at normal pressures, because ice melts into water, and it is the water which later boils. At very low pressures, around 6/1000 (MORE)

Do you need to boil the water before making the ice cubes?

This will depend on the source of your water. In most developed countries, it is not necessary to boil water before freezing it for ice cubes because the water is safe to drin (MORE)

Is it possible to have boiling ice water?

It is possible to have boiling ice water. If the pressure is  increased enough, the melting temperature will also increase (the  bonds would need more energy to break). Some (MORE)
