How is the pressure of a gas related to its concentration of particles? a) pressure will expand a gas, enlarging its volume and reducing its density and concentration of particles. b) pressure will magnify a gas, developing its volume and multiplying its density and concentration of particles. c) pressure will compress a gas, reducing its volume and giving it a greater density and concentration of particles. d) pressure will accelerate a gas, extending its volume and allowing a smaller density and concentration of particles.

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
