Pressure and volume

• As volume doubles the pressure halves. As pressure doubles the volume halves. This is an inversely proportional relationship
• As you decrease volume, there is less space for the particles to travel and this means they hit the container walls more often and the pressure is aid to increase
• As you increase volume of a container the pressure decreases as there is more space for the particles to go into and so they hit the walls less
• To find pressure the equation is: Pressure(Pa) x volume (m cubed)= a constant PV=K
• For a gas at constant temperature, pressure multiplied by volume is also constant
• P1V1=P2V2

  This describes the relationship between Pressure and Volume at depths in a liquid. It says that pressure x volume acting upon an object will be equivalent no mater the depth
