A container with no insulation has two compartments. The first compartment is evacuated to zero pressure, and the other contains a compressed gas that is not an ideal gas. Supposed the separation between the two compartments is removed. What type of process is this? A- isobaric
B- isovolumetric
C-adiabatic
D-isothermal

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?
