1 g of steam at

{100^\mathrm{o}}C

melts how much ice at

{0^\mathrm{o}}C

[Latent heat of ice = 80 col/gm] and latent heat of steam = 540 cal/gm]

View answer and explanation

Correct option: D

8 gm

Option D (8 gm) is correct because the heat released by the steam condensing and cooling to 0°C is used to melt the ice.
