Homework Statement
Find mi, the initial mass of ice.
Ti = -20
ci = 2093Jkg-1K-1
Ts = +35
ms = 2kg
cs = 837.4Jkg-1K-1
cw = 4187Jkg-1K-1
lf = 3.35x105Jkg-1
S = solid
W = water
I = ice
lf = latent heat of fusion of ice / water
Homework Equations
Q=mc[tex]\Delta[/tex]T
Q=C[tex]\Delta[/tex]T
Q=ml
The Attempt at a Solution
For the Solid
Qs = (2)(837.4)(10-35)
Qs = -4.187x104J
For the Water / Ice
Qi = mix(4.186x104)
Q = mix(3.35x105)
Qw = mix(4.187x104)
I don't know where to go from here, I have seen the markscheme however and I am aware that the answer is: mi = 0.100kg
