It takes 20 min to melt 10g of ice

WebWe know the ice cube weighed 10 grams initially, and we know it's density (1g/cm^3), so let's apply the formula to determine how much volume the melted ice cube takes. The answer is 10 cubic centimeters (10g / 1g/cm^3 = 10cm^3), which is exactly the same volume as the water that was initially displaced by the ice cube. Web17 jun. 2013 · Surface area changes the TIME it takes to melt but doesn't change the amount of heat required to melt. I don't know where you got the idea that it requires more heat to melt 10 g than 20 g. And you are right, it IS the opposite. If it takes x amount of heat to melt 10 g it must take 2x to melt 20 grams or 3x to melt 30 g.
