--- Quote from: spookyjaransh on November 03, 2009, 09:54:52 am ---the constant here is = (1000/2.5) =400.
there fore after 1 stroke the volume increases by 100 cm3, thus new volume = 1100.
but because the constant does not change, therefore, 1100/x = 400
=> x = 1100/400 = 2.75 atm.

hey ansh!!!
u've done one thing wrong here....
according to the boyle's law constant = pressure*volume
so, k=1000*2.5 = 2500
thus,
p= k/v
=>p=2500/1100
=>p=2.27 atm

am i right sir???

astarmathsandphysics:
You were supposed to work out the volume of the air I think when the pressure is reduced from 2.5 atm to 1.

Ghost Of Highbury:
is it 2500/2600 = 0.9?

that was the first part...i think nid said she wanted help in the second part...
