Required information

An ideal Otto cycle has a compression ratio of $8.$ At the beginning of the compression process, air is at $95$kPa and $27C,$ and $770k\frac{J}{k}g$ of heat is transferred to air during the constant$-$volume heat$-$addition process. Take into account constant specific heats at room temperature. The properties of air at room temperature are $c_p=1\mathrm{.}005k\frac{J}{k}g*K,c_V=0\mathrm{.}718k\frac{J}{k}g*K,R=0\mathrm{.}287k\frac{J}{k}g*K,$ and $k=1\mathrm{.}4.$

Determine the pressure and temperature at the end of the heat$-$addition process. $($You must provide an answer before moving on to the next part.$)$
