Boyle's law states that when a sample of gas is compressed at a constant temperature, the pressure p and volume v satisfy the equation pv = c, where c is a constant. suppose that at a certain instant the volume is 400 cm3, the pressure is 160 kpa, and the pressure is increasing at a rate of 40 kpa/min. at what rate is the volume decreasing at this instant?

Consider the particle-in-a-box problem in 1d. a particle with mass m is confined to move freely between two hard walls situated at x = 0 and x = l. the potential energy function is given as (a) describe the boundary conditions that must be satisfied by the wavefunctions Ď(x) (such as energy eigenfunctions). (b) solve the schr¨odingerâs equation and by using the boundary conditions of part (a) find all energy eigenfunctions, Ďn(x), and the corresponding energies, en. (c) what are the allowed values of the quantum number n above? how did you decide on that? (d) what is the de broglie wavelength for the ground state? (e) sketch a plot of the lowest 3 levelsâ wavefunctions (Ďn(x) vs x). donât forget to mark the positions of the walls on the graphs. (f) in a transition between the energy levels above, which transition produces the longest wavelength Îť for the emitted photon? what is the corresponding wavele
