Suppose an experiment measures a mass, heats it over a flame without changing its state, measures it again, and finds the mass to be different. which statement best describes the kind of change that could have taken place a. physical change because the substance became more denseb. chemical change because mass was lost, most likely as a gasc. chemical change because the chemical property of mass changedd. physical change because the mass melted going from a solid to a liquid

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?
