A technician is testing vacuum pumps. The pumps are connected to a vacuum chamber with a volume of 1.50 m3, allowed to run for a set period of time, and the temperature and pressured measured. For a particular pump, the final chamber temperature and pressure are respectively measured to be 310 K and 3.50×10−10 Torr (where 1 Torr = 133 Pa). Determine the number of molecules in the chamber at the end of the pumping time. You may treat the contents of the vacuum chamber as an ideal gas. molecules

A teapot with a surface area of 715 cm2 is to be plated with silver. It is attached to the negative electrode of an electrolytic cell containing silver nitrate (Ag+NO3−). The cell is powered by a 12.0−V battery and has a resistance of 1.30 Ω. If the density of silver is 1.05×104 kg/m3, over what time interval does a 0.133−mm layer of silver build up on the teapot? h

In a MOSFET, the two-dimensional density of electrons on the surface of a semiconductor is controlled by a voltage applied to a gate that is separated by an insulator from the semiconductor: n = CVg/eA, where C is the capacitance and A is the area of the semiconductor. Consider a MOSFET with area = 10−7 m2 and capacitance = 30 pF = 30×10−12 F in a 0.2 T magnetic field. a) What gate voltage corresponds to filling of one Landau level? b) What is the energy splitting (ΔE) between Landau levels (of the same spin) at this magnetic field? (Assume the effective mass = 0.07 me, the value for GaAs.) What must be the temperature so that there is no thermal excitation into the second Landau level?
