WebQuestion: Be sure to answer all parts. Calculate the heat absorbed when 591 g of ice at −11.4∘C melts and then the water is converted to steam at 147.0∘C. The specific heat of ice is 2.03 J/(g∘C), the heat of fusion of ice is 6.01×103 J/mol, the specific heat of water is 4.18 J/(g∘C), the heat of vaporization of water is 4.07×104 J/mol, and the specific heat of steam WebRound the answer to two significant figures. Use the equation shown below, where c is the specific heat of aluminum, 0.897, m is the mass of the pan, 580 g, the initial temperature is 25∘C, and the final temperature is 150∘C. q= (580 g) (0.897Jg∘C) (150∘C−25∘C) q=65,032.5 J. Converting to kilojoules, and rounding to two significant ...
