pressure

     

Pressure (symbol: 'p') is the force over an area applie to an object in a direction perpendicular to the surface. Gauge pressure is the pressure relative to the local atmospheric or ambient pressure.

Trivia about pressure

  • According to Boyle's Law, when a gas is compressed to half its size, this doubles
  • (Sarah of the Clue Crew) The main danger of submarine flooding is being dragged down too deep to expand this
  • (Let's hear from someone at USC): "Hi, I'm George Olah, Nobel Prize winner in chemistry.The "P" in Boyle's Law, PV=K, stands for this"
  • When you are "under" this, a manometer will measure it
  • Metamorphic rocks are divided into 2 main types depending on how they were formed: by heat or by this
  • (Sarah of the Clue Crew gives the clue as she and Kelly demonstrate a potato gun.) A potato gun demonstrates Boyle's Law using a simple tube & a stick; pushing the stick reduces the volume of air and increases this 8-letter term, making the potato go ballistic
  • Heat a soda can with 1 tsp. of water in it, then invert it in a pot of water & it'll collapse by atmospheric this
  • (Jon of the Clue Crew releases a balloon.) Thrust comes from the sudden inequality of this, sometimes measured in atmospheres, inside & outside a rocket
  • The Titanic sank with its artifacts to 12,500 feet, where this is measured at about 380 atmospheres
  • Dalton's law says that the total amount of this exerted by a mix of gases is the sum of what each gas would exert alone
