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 =?

Expert Solution

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,

It is well known that water freezes at 0°C at atmospheric pressure. The mixture of liquid water and ice at 0°C is said to be at stable equilibrium since it cannot undergo any changes when it is isolated from its surroundings. However, when water is free of impurities and the inner surfaces of the container are smooth, the temperature of water can be lowered to 22°C or even lower without any formation of ice at atmospheric pressure. But at that...

Suppose the market for frozen orange juice is in equilibrium at a price of $2.00 per can and a quantity of 4200 cans per month. Now suppose that at a price of $3.00 per can, quantity demanded falls to 3000 cans per month and quantity supplied increases to 4500 cans per month. Draw the appropriate diagram for this market. Calculate the price elasticity of demand for frozen orange juice between the prices of $2.00 and $3.00. Is the demand elastic...
