A liquid sample from a black oil reservoir had a volume of 227.0 cu cm in alaboratory cell at reservoir temperature and bubble point pressure. The liquid wasexpelled through laboratory equipment, which is the equivalent of the fieldseparator–stock tank system. The oil volume collected in the stock tank was 167.4cc. The separator produced 0.537 scf of gas, and the stock tank produced 0.059 scfof gas. Calculate the formation volume factor of the oil and the solution gas-oilratio.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
