What is the specific latent heat for ice?....Take a look at details below..?
A pupil adds 37 g of ice at #0^oC# to 100 g of water at #30^oC# . The final temperature of water and ice is #0^oC.# No heat is lost or gained from the surroundings.
The specific heat capacity of water ios 4.2 J/#g^oC# .
What is the specific latent heat for ice?
A 47 J/g
B 341 J/g
C 4700 J/g
D 12600 J/g

1 Answer
B
Explanation:
Assuming that in the final mixture of ice and water, all the ice is melted and becomes water at
Heat gained by ice at
where
Heat lost by water at
Inserting varius values we get
Using Law of conservation of energy and equating (1) and (2) we get
