question_answer 1)

What will be the minimum pressure required to compress \[500\text{ }d{{m}^{3}}\]of air at 1 bar to \[200\text{ }d{{m}^{3}}\]at \[30{}^\circ C\]?

Answer:

At constant temperature Boyle's law can be applied: \[{{P}_{1}}{{V}_{1}}={{P}_{2}}{{V}_{2}}\] \[1\times 500={{P}_{2}}\times 200\] \[{{P}_{2}}=2.5bar\]
