A sealed cubical container $26\mathrm{.}0$ cm on a side contains a gas with four times Avogadro's number of argon atoms at a temperature of $25\mathrm{.}0\backslash$deg C$.$ HINT $($a$)$ Find the internal energy $($in J$)$ of the gas. J $($b$)$ The total translational kinetic energy $($in J$)$ of the gas. J $($c$)$ Calculate the average kinetic energy $($in J$)$ per atom. J $($d$)$ Use P $=23$ N V $12$ mv$2$ to calculate the gas pressure $($in Pa$).$ Pa $($e$)$ Calculate the gas pressure $($in Pa$)$ using the ideal gas law $($PV $=$ nRT$).$ Pa
