Chapter 3: Q12DQ (page 609)

Comment on the following statement:When two gases are mixed, if they are to be in thermal equilibrium, they must have the same average molecular speed.Is the statement correct? Why or why not?

Short Answer

Expert verified

This statement is incorrect. Two gases mixed in the thermal equilibrium will have equal kinetic energy but no speed.

Step by step solution

01

About Thermal Equilibrium

Two systems in contact that are at the same temperature and are experiencing no net heat flow between them, are said to be in thermal equilibrium.

02

Determine the average molecular speed when two gases are mixed in thermal equilibrium

This statement is incorrect. Two gases in the thermal equilibrium will have equal kinetic energy but not speed, heaviergaswill move slower. In the air nitrogenmovesfaster than oxygen.

Therefore, two gases in the thermal equilibrium will have equal kinetic energy but no speed.

How can the thermal conduction of heat from a hot object to a cold object increase entropy when the same amount of heat that flows out of the hot object flows into the cold one?

What would be the efficiency of a Carnot engine operating with TH=TC? What would be the efficiency if TC=0Kand THwere any temperature above 0K? Interpret your answers.

You hold an inflated balloon over a hot-air vent in your house and watch it slowly expand. You then remove it and let it cool back to room temperature. During the expansion, which was larger: the heat added to the balloon or the work done by the air inside it? Explain. (Assume that air is an ideal gas.) Once the balloon has returned to room temperature, how does the net heat gained or lost by the air inside it compare to the net work done on or by the surrounding air?

-18.22 (a) If you apply the same amount of heat to 1.00 mol of an ideal monatomic gas and 1.00 mol of an ideal diatomic gas, which one (if any) will increase more in temperature? (b) Physically, why do diatomic gases have a greater molar heat capacity than mono-atomic gases?

The prevailing winds on the Hawaiian island of Kauai blow from the northeast. The winds cool as they go up the slope of Mt. Waialeale (elevation 1523 m), causing water vapor to condense and rain to fall. There is much more precipitation at the summit than at the base of the mountain. In fact, Mt. Waialeale is the rainiest spot on earth, averaging 11.7 m of rainfall a year. But what makes the winds cool?
