Question

how much steam at 100C will just melt down 3200g of ice at - 10⁰C?

GIVEN
Specific heat capacity of ice - 2100 J kg-¹C-¹
Specific beat capacity of water - 4200 J kg-¹C-¹
Specific latent heat of steam = 2260 x 10³J kg-¹
Speafie latent heat of ice - 336 x 10³ J kg‐¹

Answer 1

Explanation:

the right answer is 425 g

Answer 2

Answer:

Amount of heat energy gained by 1kg of ice at −10°C to raise its temperature to 0°C = 1 × 2100 × 10 = 21000 J

Amount of heat energy gained by 1kg of ice at 0°C to convert into water at 0°C = L

Amount of heat energy gained when temperature of 1kg of water at 0°C rises to 100°C = 1 × 4200 × 100 = 420000 J

Total amount of heat energy gained = 21000 + 420000 + L = 441000 + L.

777000J.
