10 gram of steam passes over a ice block at zero degree celsius what amount of ice melt
Answers
Answer:
80 gram
Explanation:
full explanation is pinned
Explanation:
For thermal equilibrium the final temperature of steam must be equal to ice i.e. zero.
The steam will go phase transition from gas to liquid, heat released is given as
Q=mL where L is latent heat of vaporization and m is mass of substance
For water L vvaporizatio =540cal/g
Q1 =10∗540=5400cal
Boiling water will change it's temperature from 100°
C to 0° C
heat released is given as
Q=mCΔTcal/g where C is specific heat capacity and ΔT is temperature difference
Q2 =10×1×(100−0);C wwate =1cal/g
total heat transferred=QQ1 +Q 2
=6400cal
This amount of heat will be used for melting the ice
6400=mL
fusion
=m80cal/g latent heat of fusion for water =80cal/g
⇒m=80g
