What will be the minimum pressure required to compress 500 dm3 of air at 1 bar to 200 dm3 temperature remaining constant?

उत्तर
V1 = 500 dm3
P1 = 1 bar
T1 = 273 K
V2 = 500 dm3
T2 = 273 K
P2= ?
`("P"_1 "V"_1)/"T"_1 = ("P"_2 "V"_2)/"T"_2`
`(500 xx 1)/273 = ("P"_2 xx 200)/273`
`"P"_2 = 500/200 = 2.5` bar
