An ideal gas has an initial pressure of 3 pressure units and an initial volume of 4 volume units. the table gives the final pressure and volume of the gas (in those same units) in five processes. Which processes start and end on the same isotherm? a b c d e __|__________________________ p | 12 6 5 4 1 V | 1 2 7 3 12

see this is a simple one
u just need to obey boyle law
(since it is given that temp. should remain const..)
so u just need to check that P1V1 = P2V2
clearly all others satisfy except (c)
hope u got it
rate me

all the best ... |

so when you say obey Boyl's law do you imply that.... PaVa = PbVb=....... where Pa represents the diff in the int.and fin. pressures?? and similarly for V

no they represent absolute pressure and volume
let me give an example from the ques
given pa = 12 and va = 1
pb = 2 and vb = 2
so pa . va = pb. vb = 12 = pd.vd = pe. ve is not equal to pc.vc
rate me

it is a,b,d,e. as in all these cases the temperatures are same as PV values are same. PaVa = PbVb = PdVd = PeVe = 12
