text: Wrong answer. The heat of fusion (transform ice to water) and heat of vaporization (water to steam) is different.\n\nThe heat of fusion for water is 334 J/g.\n\nThe heat of vaporization for water is 2260 J/g.\n\n\nTo calculate the heat needed:\n\nHeat required = 2260 J/g x 50 g = 113,000 J\n\n\nI never understood the significant figures crap. Maybe someone else can do that part.
