If 120g of steam of temperature 100°c is released on an
ice slab of temperature 0°c, how much ice will melt ?​

Answer 1

Explanation:

The heat exchange must be calculated in several steps:

1. The heat lost by the steam to the ice when the steam condenses

2. The heat gained by the ice when it melts

3. The heat lost by the condensed steam to the original water as the temperature of the condensed steam equalizes with that of the water.

Part 1: The heat released by the steam as it condenses:

ΔH1 = (mass of steam)(latent heat

Answer 2

Answer:

Let the mixture become water at T

o

C at steady state.

To convert steam at 100

o

C to water at T

o

C

Q=1×540+1×1×(100−T)

Similarly, to convert 1 g of ice to water at T C

Q=1×80+1×1×(T−0)

Since, both these heats should be the same,

540+100−T=80+T

⟹2T=560

⟹T=280

o

C

Since, this is not a possible value of T hence water wont exist and it will be precisely steam at 100

o

C
