Question
For the following statements, choose the word or words inside the parentheses that serve to make a correct statement. Each statement has at least one and may have more than one correct answer. For a sample of an ideal gas, the product pV remains constant as long as the (temperature, pressure, volume, internal energy) is held constant. The internal energy of an ideal gas is a function of only the (volume, pressure, temperature). The Second Law of Thermodynamics states that the entropy of an isolated system always (increases, remains constant, decreases) during a spontaneous process. When a sample of liquid is converted reversibly to its vapor at its normal boiling point, (q, w, Delta p, Delta V, Delta T1, Delta U, Delta H, Delta S, Delta G, none of these) is equal to zero for the system. If the liquid is permitted to vaporize isothermally and completely into a previously evacuated chamber that is just large enough to hold the vapor at 1 bar pressure, then (q, w, Delta U, Delta H, Delta S, Delta G) will be smaller in magnitude than for the reversible vaporization.Explanation / Answer
A. For a sample of an ideal gas the product pv remains constant as long as temperature is held constant.
B. The internal energy of an ideal gas is a function of temperature only.
C. The second law of thermo dynamics states that the entropy of an isolated system always increase during an spontaneous change.
D. When a liquid is converted reversibly to its vapour at its normal boiling point delta T1 is equal to zero for the system.
E. If the liquid is permitted to vapourize isothermally and completely into a previously evacuated chamber that is just large enough to hold the vapour at 1 bar then q will be smaller in magnitude than for the reversible vapourization.
