Ответ:
129 g of ice would be melted by the energy obtained as 16.1![^{0}\textrm{C}](/tpl/images/0137/1545/084eb.png)
Explanation:
Total amount of heat obtained as 16.1 g of steam is condensed at 100
and cooled to 0
= [heat released during condensation of steam]+[heat released during cooling of steam to 0
]
So, Total amount of heat obtained as 16.1 g of steam is condensed at 100
and cooled to 0
= [
= 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.
