Pressure in Gases (collapsing can practical)

  1. Before you start heating

  • Pressure is equal inside and outside the can

  • Water inside starts to heat up

  1. Steam comes out

  • Water becomes steam and starts to evaporate

  • Pressure stays the same as the steam is able to leave the can

  1. The can collapses

  • Steam cools suddenly and cannot escape (condenses into water)

  • Pressure decreases suddenly (atmospheric pressure is higher) and so the can crushes
