If 2.00 m3 of water at 0∘C is frozen and cooled to -9.0 ∘C by being in contact with a great deal of ice at -9.0 ∘C, estimate the total change in entropy of the process. Delta S =?
GIVEN:
The volume of water is given by,
The water at is frozen and cooled to
The density of water is
Latent heat of fusion,
Specific heat of ice,
SOLUTION: The ice at frozen and cooled to can be considered as a change in the state of ice to water at and decrease in temperature from .
For the change in state, , Where m is the mass and L is the latent heat of fusion in J/kg
The change in entropy in changing the temperature is given by,
Where m is the mass and C is the specific heat capacity.
The total change is given by,
