Question

The following curve represent adiabatic expansions of gases `He,O_(2)`,and `O_(3)` not necessarily in order. Which curve represnets for `O_(3)`?

A. `I`
B. `II`
C. `III`
D. Any one of these

Answer 1

`pV^(gamma) =` constant or `log P =- gamma log V`
`gamma` is slope for `P-V` plots for `He, O_(2)` and `O_(3)`, i.e., `(5)/(3),(7)/(5)`and `(4)/(3)`, respectively.
