  3. Air pressure is measured with Barometer. Pressure gauge Bourdon gauge

  4. Soalan exam trial Kelantan 2011 Air particles and density are less. Less pressure Example: Peak of the mountain Sea level = 1 atmosphere If more air, so its denser. (air pressure is greater)

  5. Factors affecting air pressure. collisions Gas particles Air pressure Force exerted Onto the wall

  6. The effect of volume on air pressure.

  7. Factors affecting air pressure

  8. Closely related to Acts in Carry out in whereby whereby Changes gas into

  10. conclusion AIR PRESSURE GASES CAUSED BY COLLISIONS AND BOUNCING OFF OF AIR PARTICLES FROM THE WALLS OF A CONTAINER IS USED IN APPLIANCES UNDER HIGH PRESSURE: 1.CHANGE INTO LIQUIDS 2. ARE STORED IN TANKS. 3. MUST BE USED WITH GREAT CARE. TO SOLVE PROBLEM SUCH AS BLOCKAGES IN SINKS AND POURING CONDENSED MILK EASILY FROM A CAN. IS AFFECTED BY: 1. VOLUME 2. TEMPERATURE
