stupid question
Temperature and Pressure
To melt it quickly add calcium chloride or ferous chloride, either will work down to -55 Celcius. You will need 43 grams per 100 g of ice for the CaCl2 and 50g / 100g if using feCl3 How quickly it melts will depend on how much mixing you do after adding the salt.
The freezing point of water decrease because the dissolution is a process which release heat.
the sun will melt it
