One mole of an ideal monoatomic gas is kept in a rigid vessel. The vessel is kept inside a chamber whose temperature is ${87}^{\circ }\text{C}$. Initially, the temperature of the gas is $4^{\circ }\text{C}$. The walls of the vessel have an inner surface of area $500{\text{cm}}^2$ and thickness of $2\text{cm}$. If the temperature of the gas increases to $8^{\circ }\text{C}$ in $5.0\text{seconds}$, find the thermal conductivity of the material of the walls.
