What will be the minimum pressur required to compress `500dm^(3)` of air at 1bar to `200 cm^(3)` at `30^(@)C` ? .

Explanation

Given `V_(1) = 500dm^(3) , P_(1) = 1`bar
`T_(1) = 30 + 273 = 303K`
`V_(2) = 200 dm^(3) , P_(2) = ? , T_(2) =T_(1)`
`:' (P_(1)V_(1))/(T_(1)) = (P_(2)V_(2))/(T_(2))`
`:. 1 xx 500 = P_(2) xx 200 or P_(2) = 2.5` bar
