how pressure is independent of volume????. bz we have boyls law to relate them.and we say in pv diagram it is independent , while we know that it looks dependent bz when we try to decrease the volume , pressure increases.

You are right, the pressure is dependent of volume and the pressure-volume diagram shows that perfectly. So that's incorrect to say that they are independent.
If we're speaking of ideal gases the Ideal Gas Law tells us that PV =
nRT where P is pressure in Pascals (or Newtons per square meters), V
is volume in cubic meters, n is the number of molecules/atoms, in
moles, which are contained (a mole is about 6.02 x 1023), R is the
universal gas constant (287 Joules per kilogram per Kelvin), and T is
temperature in Kelvins.

sorry , ur wrong , it is independent.however uor right in the part
that pressure volume diagram shows that perfectly provided the
temperature remains constant.
