i have capsule filled with oil ( density 0.8 ) with atm.temp. initial pr. at the time of filling 1bar.finalpr?

Question

i have capsule filled with oil ( density 0.8 ) with atm.temp. initial pr. at the time of filling 1bar.final pr? when volume difference considered as 0.02684 cc & final temp of oil be supposed to increase by 1ºC..

can anybody help me to find out final pressure of air inside capsule which was compressed due to oil?
given data:
initial wt. of capsule 100 miligram
after filling oil 80% in capsule,wt. of capsule = 525.16 mg
after making hole on air side of casule,some air will be released at that time wt. of capsule = 491.61 mg
initial temp of air is atmospheric
length of capsule = 18 mm
diameter of capsule = 7.34 mm
if anybody find final pressure of air present inside the capsule before making hole i.e. when capsule weight was 525.16 mg i will be thank to that person. can anybody help me?...if u have any further missing data pl. ask me..thanks.

Answer 1

I'm happy that you that capsule filled with oil.
If you are looking for its volumetric coefficient of expansion then

dV=V Cv (T2-T1)


T1- initial temperature
T2- final temperature
Cv - coefficient of expansion
V - volume
dV change in volume

I hope it helps.
