You are given 84.27241 g of a substance initially at 293.89622K. It is heated first to its freezing point, 357.72232 K, andthen to its boiling point, 496.31828 K. The heat capacity ofthe solid form is 31.92123 J/g-K and the heat capacity of theliquid is 8.21936 J/g-K. The heat of fusion is 81.9355 J/gand the heat of vaporization is 80.66671 J/g.
If heat is supplied to the system at a constant rate of 36.80519J/s, how long will it take to completely vaporize the substance? Give your answer in minutes.
