The second part of the question needs help.
Q.The air in a bicycle tyre has a volume of 1000cm3 and a pressure of 2.5 atmospheres. If the air is released ( at the same temperature) so its pressure is 1 atmosphere, what is the volume of the air?

This part needs help

A bicycle has a volume of 100cm3 and is now used to pump up the tyre. After 1 stroke of the pump, what is the presure in the tyre?

spookyjaransh:
so wats the correct answer then?? ???

astarmathsandphysics:
pV=k so 2.5*1000=k so V=2500/p but p is now 1atm so V=2500cm£

Some of the air escaped to the atmosphere
