The volume, V, of a gas varies inversely as the pressure, P, on it. If the volume is 160 cm3 under pressure of 30 kgcm2 , what pressure has to be applied to have a volume of 750 cm3? k=

P=kgcm2

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
