  • A whale takes a breath at the surface of the ocean, where the pressure is 1.00 x 105 Pa. It then dives to a depth where the pressure is 1.21 x 105 Pa. The temperature is the same at twhat is the volume of bubble when it reaches the surface?
    41.3 cm^3
  • Let's make a crazy dance!
    Yessss!
  • Walk like a crab! Hahahaha!
    Walk like a crab! Hahahaha!
  • If I double the volume, what happens to the pressure ?
    halved !
  • Boyle's Law
    PV= K or P1V1 = P2V2
  • Describe the behaviour of gas molecules
    move random directions / collide with each other / random speed
  • if half particles of gas are removed, what happens to the temperature ?
    same
  • if half particles of gas are removed, what happens to the density ?
    halved !
  • T/F: Pressure is proportional to volume.
    False
  • Do the floss!
    hahahahahahah
  • If I Double the Pressure, what happens to the volume ?
    Halved
