How many grams of ice would be melted by the energy obtained as 16.1 g of steam is condensed at 100°C and cooled to 0°C? specific heat (ice) = 2.10 J/gºC specific heat (water) = 4.18 J/gºC heat of fusion = 333 J/g heat of vaporization = 2258 J/g 43.1 kg 36.4 kg 129 g 6.73 kg 20 g

Answer:

129 g of ice would be melted by the energy obtained as 16.1 [tex]^{0}\textrm{C}[/tex]

Explanation:

Total amount of heat obtained as 16.1 g of steam is condensed at 100 [tex]^{0}\textrm{C}[/tex] and cooled to 0 [tex]^{0}\textrm{C}[/tex] = [heat released during condensation of steam]+[heat released during cooling of steam to 0 [tex]^{0}\textrm{C}[/tex]]

So, Total amount of heat obtained as 16.1 g of steam is condensed at 100 [tex]^{0}\textrm{C}[/tex] and cooled to 0 [tex]^{0}\textrm{C}[/tex] = [[tex][16.1\times 2258]J+[16.1\times 4.18\times (100-0)]J[/tex] = 43083.6 J

To melt 1 g of ice, 333 J of heat is required. Therefore 43083.6 J of heat would melt (43083.6/333) g of ice or 129 g of ice.
