In the figure, suppose the switch has been closed for a time sufficiently long for the capacitor to become fully charged. Find (a) the steady-state current in each resistor and (b) the charge Q on the capacitor. (c) The switch is now opened at t = 0. Write an equation for the current IR2 through R2 as a function of time and (d) find the time interval required for the charge on the capacitor to fall to one-fifth its initial value. R2 should say 19 kiloohm in the figure.

The enthalpy of vaporization of a liquid is 14.4 kJ at 180K, its boiling point at 1 bar. The molar volumes of the liquid and the vapor at the boiling point are 115 cm³ mol-¹ and 14.5 liter mol-¹, respectively. a. Use the Clapeyron equation to estimate d/d at the boiling point. b. Now use the Clausius-Clapeyron equation to calculate dP/T at the boiling point. C. What is the percent error in P/T when using the Clausius-Clapeyron equation? dT d. What approximations in the derivation of the Clausius-Clapeyron equation lead to the error in this estimate?

2 A 200-L tank contains krypton at a pressure of 1335 psi (9312kPa) at 70°F (21.1°C). The gas is labeled with 85Kr to a specific activity of 2 Ci per Kr. The krypton is leaking out of the tank at a rate of 1 mL (at STP) per minute. The tank is in a storage room 3 m x 3 m x 2 m high, and the air in the room is exchanged four timer per hour. What is the steady-state concentration in the room, in uCi/cm3 and Bq/m3?
