It's spelled piezo.\n\nA material which exhibits the piezo-electric effect produces a voltage across one axis when struck or flexed in another axis.  \n\nIn gas stove and barbecue lighters and the pens which you speak of the resultant voltage is stepped up via a transfomer.\n\nThe same effect is used in "crystal" microphones and was used in crystal pick-up cartridges.

A vacuum is a volume of space that is substansively empty of matter, so that gaseous pressure is much less than standard atmospheric pressure. The root of the word vacuum is the Latin adjective vacuus which means "empty," but space can never be perfectly empty. A perfect vacuum, known as "free space", with a gaseous pressure of absolute zero is a philosophical concept with no physical reality, not least because quantum theory predicts that no volume of space is perfectly empty in this way. Physicists often use the term "vacuum" slightly differently. They discuss ideal test results that would occur in a perfect vacuum, which they simply call "vacuum" in this context, and use the term partial vacuum to refer to the imperfect vacua realized in practice.

Moving air is in a sense a fluid. Air is also a composition of matter (nitrogen, oxygen, etc.). These materials can and do conduct heat. Also heat travels upwards in air. This is because colder air has a different partial pressure.

A pressure is defined to be a measurement of the amount of force acting on an object per unit area\n\nP = F / A   the S.I units for pressure are the N / m^2 which is also called a Pascal (Pa)

I think you talk about a Paintball Marker Tank. They are High Pressure Air Tanks, can shoot paintballs. 3000 psi is near 210 Bar (Atmosphere). It means Its not a toy :D

As the air pressure decreases around it, the air, if contained in a flexible enclosure, would expand, pushing the sides of the container outward. IE: a balloon getting bigger. But I'm not sure what you mean by a "parcel" of air.

Air dusters.  They are cans of pressurized air that are used to dust things that are not easy to clean with a regular duster.

All Pneumatic tools are powered by an air compressor, much like the tools powered by other sources like electricity, gas, etc.

Define high pressure. Define high capacity.\n\nAre these reciprocating or centrifugal compressors?

What do you mean by "unload"?  An air compressor works by taking air and basically compressing it into a tank.  The amount of pressure in the tank and coming out of the lines is controlled by two different valves, the tank pressure valve and the use valve.  Both valves have limits and most equipment states how much pressure they need.  I used a compressor to spray lacquers at work.  The thicker the lacker the higher the pressure I use to make sure the lacquer spreads niceley and doesn't bubble.
