The entropy of a gas is larger than that of the liquid because the specific volume of gas is greater thus implying more mutual configurations are allowed for molecules in a gas than in the corresponding liquid.
Assume that the metal rack is cooled from 240°F to 85°F, the temperature of the outlet water. The amount of heat removed from the retort walls in cooling from 240 to 100°F is 10 000 btu. Radiation loss from the retort during cooling is estimated a..

What is the maximum concentration (in M) of chloride ions in the solution that contains 0100 M Pb2 +? The Ksp for lead (II) chloride is 1.0 x 10-4.
Explain why bubbles are observed to emerge from the jar when it is in the boiling water. b. Explain why the lid "pops down" on the jar top soon after removing the jar from the boiling water.
In an acid-base titration experiment, a 0.2 M solution of HCl was titrated at 25°C with a 0.05 M solution o KOH. Here the equilibrium constant for the titration reaction had this value:
Describe the predicted effect on glycine biosynthesis in a mutant mammalian cell if there is a mutation in the 5'-IRE sequence of ferritin mRNA that reduces the Ka of IRP binding as compared t binding with wild-type mRNA
