Question

phase change

Answer 1

1a)draw the graph showing the way the temperature changes as stream condenses
from a ice
b)calculate the amount of water(mass) that has been frozen?

Answer 2

for a) i think this is the graph

Answer 3

for b i am not sure where to start i only have is L=33.4kJ/g

Answer 4

The graph is correct, though I'm guessing you may want to invert it is steam -> ice, not ice -> steam. For par b, the relevant equation here is that of latent heat:
\[Q=mL\]
Or the amount of heat added/removed from a substance equals its mass times its specific latent heat. Are you sure you don't have more concrete numbers to calculate Q?
