Option: 1

\mathrm{160\: k}


Option: 2

\mathrm{170\: k}


Option: 3

\mathrm{200\: k}


Option: 4

\mathrm{20\: k}

For a reversible isobaric process, the equation relating temperature and volume is:

\mathrm{ \frac{V_1}{T_1}=\frac{V_2}{T_2} }

Given:

\mathrm{ V_1=0.05 \mathrm{~m}^3 }

\mathrm{ V_2=0.02 \mathrm{~m}^3 }

\mathrm{ T_1=400 \mathrm{~K} }

Solving for \mathrm{ T_2 : }

\mathrm{T_2 =\frac{V_2}{V_1} \cdot T_1 }

\mathrm{T_2 =\frac{0.02 \mathrm{~m}^3}{0.05 \mathrm{~m}^3} \cdot 400 \mathrm{~K} }

\mathrm{T_2 =160 \mathrm{~K} }

Therefore, the correct option is 1.
