Answer
$- {\text{8}}{\text{.2}} \times {\text{1}}{{\text{0}}^4}{\text{ J}}$
Work Step by Step
\[\begin{gathered}

{\text{Volume of gas produce = 0}}{\text{.75 }}{{\text{m}}^3} \hfill \\
{\text{Pressure (constant) = 110}}{\text{.0 kPa}} \hfill \\

{\text{ = }} - {\text{(110}}{\text{.0kPa)(0}}{\text{.75 }}{{\text{m}}^3} - {\text{ 0 }}{{\text{m}}^3}) \hfill \\
{\text{ = }} - {\text{82}}{\text{.5 kPa}} \cdot {{\text{m}}^3} \hfill \\
{\text{The initial volume is 0 }}{{\text{m}}^3}{\text{ because initially,}} \hfill \\
