A monatomic ideal gas is contained in a rigid container of volume V with walls of total inner surface area A, thickness x and thermal conductivity K. The gas is at an initial temperature t_(0) and pressure P_(0) . Find the pressure of the gas as a function of time if the temperature of the surrounding air is T_(s) . All temperature are in absolute scale.

A rod of length l with thermally insulated lateral surface consists of material whose heat conductivity coefficient varies with temperature as k= a//T , where a is a constant. The ends of the rod are kept at temperatures T_1 and T_2 . Find the function T(x), where x is the distance from the end whose temperature is T_1 .
