Final temperature is 33.58 °C
Explanation:
Specific heat of steam = 2.010 KJ
Latent heat of ice = 336 J/g
Heat released by 200 gm steam,
The heat gained by ice at 0 °C ,
J
Heat gain by steam at 0°C to convert to steam at T degree celcius is,
Heat lost = heat gained,
40200 - 402 T = 67200 + 402 T
-804 T = 27000
T = - 33.58 °C
