Question

An 10 g ice cube at -13˚C is put into a Thermos flask containing
115 cm^{3} of water at 20˚C. By how much has the entropy of
the cube-water system changed when a final equilibrium state is
reached? The specific heat of ice is 2200 J/kg K and that of liquid
water is 4187 J/kg K. The heat of fusion of water is 333 ×
10^{3} J/kg.

Answer #1

An 11 g ice cube at -12˚C is put into a Thermos flask containing
145 cm3 of water at 24˚C. By how much has the entropy of
the cube-water system changed when a final equilibrium state is
reached? The specific heat of ice is 2200 J/kg K and that of liquid
water is 4187 J/kg K. The heat of fusion of water is 333 ×
103 J/kg.

An insulated Thermos contains 115 g of water at 78.7 ˚C. You put
in a 10.0 g ice cube at 0.00 ˚C to form a system of ice +
original water. The specific heat of liquid water is 4190
J/kg•K; and the heat of fusion of water is 333 kJ/kg. What is the
net entropy change of the system from then until the system reaches
the final (equilibrium) temperature?

An insulated Thermos contains 113 g of water at 77.3 ˚C. You put
in a 10.3 g ice cube at 0.00 ˚C to form a system of ice + original
water. The specific heat of liquid water is 4190 J/kg•K; and the
heat of fusion of water is 333 kJ/kg. What is the net entropy
change of the system from then until the system reaches the final
(equilibrium) temperature?

You decide to put a 40.0 g ice cube at -10.0°C into a well
insulated coffee cup (of negligible heat capacity)
containing of water at 5.0°C. When equilibrium is
reached, how much of the ice will have melted? The specific heat of
ice is 2090 J/kg ∙ K, that of water is 4186 J/kg ∙ K, and the
latent heat of fusion of water is 33.5 × 104 J/kg.
