1. How much heat is required to melt 25.0 g of ice at 0°C?
tigry1 [53]

Answer: The heat required to melt 25.0 g of ice at 0^0C is 8350 Joules

Explanation:

Heat of Fusion tells us how much energy is needed to convert 1g of a solid to a liquid at the same temperature.

Q=m\times L

Q = Heat absorbed = ?  

m = mass of ice = 25.0 g

L = Latent heat of fusion of ice = 334 J/g

Putting in the values, we get:

Q=25.0g\times 334J/g=8350J

Thus heat required to melt 25.0 g of ice at 0^0C is 8350 Joules
