$($a$)$ An ideal gas maintained at a constant pressure of $219$ kPa receives $6\mathrm{.}9102$ J of heat. If the internal energy of the gas increases by $452$ J$,$ determine the change in volume of the gas. m$3($b$)$ What is the change in volume if the increase in internal energy is $6\mathrm{.}9102$ J$?$ m$3$
