Answer

$P=51.875$ Pa

Work Step by Step

As per the given problem, we have: $P=k\dfrac{T}{V}$ Here, $k$ is defined as constant of proportionality Plug the given values in the above expression, we get $33.2=k\dfrac{400}{100}$ This gives $k=8.3 paLk^{-1}$ $P=8.3 \dfrac{500}{80}$ $\implies P=51.875$ Pa
