Solution Summary

The solution calculates the amount of ice melted using the latent heat of fusion of ice.

A 10-2 kg ice cube, initially at zero degrees C, melts in the Atlantic Ocean, where the water temperature is at 10 degrees C. After melting, the ice melt heats up to match its 10 degree C environment. (The latent heat of fusion = 333J/g and the specific heat = 4.18 J/(g K).
Find the change in entropy of
(a) The water tha

Calculate the latent heat of fusion from the heat balance equation. Compare this value with the value given in the textbook.
1. What would the temperature of the calorimeter mixture be if you added too much ice and not all of it melted?
2. What affect would there be on the calculated value of L if we read the final mixtu

How many kilojoules of heat are required to melt an ice cube having the dimensions 3.8 cm x 2.8 cm x 2.1 cm? The density of ice is 0.92 g/cm^3 (cubed). Refer to table:

Suppose you add 113.1 grams of ice to 200.1 grams of water in an insulated cup, where the water is initially at 34.9 oC. How many grams of ice remain after the system reaches thermal equilibrium?
The heat capacity of water is 4.184 J/goC and the enthalpy of meltingice is 334 J/g. If all the ice is melted, just enter 0.00

1. An iron all of 1500 gm, mass and temperature 100°C is dropped into the cavity of a large block of ice. If specific heat of iron is 0.11, how much ice will be melted?
2. How much heat is generated, if 230g of ice at is melted at 10°C find the resulting water boiled and formed into steam at 120°C, [Specific heat of ice, i

100 g of ice is melted at 0 degree C, and the resulting water is warmed to room temperature (25 degree C). Calculate delta S (change in entropy) for this whole process and comment on the relative magnitude of the entropy changes for the two steps. Explain the sign of delta S.
