A tank of $7$ m$3$ volume contains argon at room temperature and $1500$ psig

pressure. $($Note: $1$ psig $=6894\mathrm{.}75728$ Pa$.)$ Determine its:

$$ Internal energy of the argon gas

$$ Enthalpy of the argon gas

$$ Specific heat capacities at constant pressure and volume

$$ Coefficient of thermal expansion

$$ Isothermal compressibility
