Carbon is allowed to diffuse through a steel plate 9.7-mm thick. the concentrations of carbon at the two faces are 0.664 and 0.339 kg of carbon per m3 of iron, which are maintained constant. if the preexponential and activation energy are 6.5 x 10-7 m2/s and 82 kj/mol, respectively, calculate the temperature (in k) at which the diffusion flux is 3.2 x 10-9 kg/(m2-s).

This is a form of winter precipitation. it is frozen precipitation falling as ice pellets. snowflakes melt into raindrops as they pass through a thin layer of warmer air. the raindrops then refreeze into particles of ice when they fall into a layer of sub-freezing air near the surface of the earth. this precipitation is called a) hail. b) rain. c) sleet. d) snow.
