Provide mechanical and molecular definitions of work and heat

minor effect on the principles being illustrated). Assume compression ratio \(=9.0: 1\); \(\alpha_{\mathrm{ig}}=695^{\circ}\left(25^{\circ} \mathrm{btdc}\right)\); flame speed factor variable; and residual fraction \(=0.050\).
\{Hint: to achieve the low intake manifold pressures stated, it is necessary to modify basic.data in the following way.
\(\begin{array}{lllllll}\text { Block } & 200 & 1.100 & 800.00 & 1.34 & 1.013 & 290.00\end{array}\)
becomes \(2 \begin{array}{llllll}200 & 1.100 & 800.00 & 1.34 & p_{\text {in }} & T_{\text {in }}\end{array}\)
Block \(550 \quad 1.100 \quad 320.0\) becomes \(550 \quad p_{\text {trapped }} T_{\text {trapped }}\).
Use \(\quad p_{\text {trapped }}=1.1 p_{\text {in }}, \quad\) and \(\left.\quad T_{\text {trapped }}=T_{\text {in }}+40\right\}\)
