How do you melt ice if the temperature is under 0 C?

Answer 1

The Celsius temperature scale is arranged by the boiling and freezing properties of water. The point at which water starts to freeze and ice starts to melt was labeled 0 degrees, and the point at which water boils was labeled 100 degrees.

Answer 2

You don't need to do anything, ice will melt normally if the temperature is higher than 0oC

Answer 3

Add salt. Salt lowers the freezing point of water, which is why they use it to de-ice roads.

Answer 4

Ice melts at 0 C. Water BOILS at 100 C. The developer of the scale (Celsius) chose the freezing point of water to be 0 C and the boiling point of water to be 100 C arbitrarily.

Answer 5

You can melt ice by applying heat to raise the temperature above 0°C. This can be done by using a heat source like a hair dryer, boiling water, or salt to lower the freezing point.
