Lava is around 1200 C. If you have 1000 kg of lava, which has a specific heat of lava is 0.84x103 J/(kg C). How many 1 kg bags of ice cubes, with a specific heat of 4186 J/(kg C) at 0 C, will it take to raise the lava temperature to 22 C? The latent heat of fusion for 334x103 J/kg. Assume the amount of melted ice equals that of ice in your calculation.
