Two equal volumes designated 1 and 2, each of which contains a quantity of a classical monatomic gas at the same temperature, are connected by a valve that is closed. If the pressures are initially unequal with P1=2P2, establish a relationship between the chemical potentials µ1 and µ2.
Give a qualitative description of the approach to equilibrium, in terms of changes in pressure and chemical potential, when the valve is opened.
What is the lenght of the driveway. An electric field = (89000 N/C, right) causes the ball in the figure below to hang at a 20° angle. The ball's mass is 4.7 g. What is the charge on ball.
A Carnot-efficiency engine operating between a reservoir of liquid mercury at its melting point and a colder reservoir extracts 15.0 J of heat from the mercury and does 4.0 J of work during each cycle. What is the temperature of the colder reservo..
A string with a mass of 31 g and a length of 2 m is stretched under a tension of 67 N. How much power must be supplied to the string to generate a traveling wave that has a frequency of 51 Hz and an amplitude of 4 cm?
A 12.0 resistor, 10.0 mH inductor, and a 50.0 µF capacitor are connected in series to a 55.0 V (rms) source having variable frequency. Find out the energy delivered to the circuit during one period if the operating frequency is twice the resonance..
