In the temperature range 310 k to 330 k, the pressure p of a certain nonideal gas is related to volume v and temperature t by p= (24.9 j/k)\frac{t}{v} t v - (0.00662 j/k ) \frac{t^2}{v} t 2 v . how much work is done by the gas if its temperature is raised from 315 k to 325 k while the pressure is held constant?

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.
