_ (I) (II) (III) (IV)
V (L) 10.5 5.25 3.5 3.3
P (atm) 1 2 3.0 3.5

Answer:
In IV observation volume is not recorded correctly.
 
As pressure andvalume are in invers relation.
 
That is straight P proportional to 1 over straight V

straight P equals space straight k over straight V
For space first space observation comma space
straight P space equals space 1
straight V equals space 10.5

For space second space observation
straight P equals space 2
That space is space is space double space of space 1 st space value
Then space straight V space must space be space half space of space fist space value.
therefore space straight V equals space 5.25

For space third space observation
straight P space equals space 3
That space is space is space triple space of space 1 st space value
Then space straight V space must space be space one space third space space of space fist space value.
therefore space straight V equals space 3.5
Now space for space forth space observation space
straight P equals space 3.5
Then space straight V space must space be space bevelled fraction numerator straight P over denominator 3.5 end fraction
therefore straight V equals space fraction numerator 10.5 over denominator 3.5 end fraction

space space space straight V equals space 3

The space correct space value space of space volume space for space forth space observation space is space 3.

Hence space forth space observation space is space not space recoded space correctly.
