Boyles law-constant temp
Example-marshmellow in the syringe
Why? because it would keep constant temperature through whole lab, even as puttin pressure on marshmellow

REAL LIFE EXAMPLE= meat injector, the reason for this is as you apply pressure to the syrange there is less room inside of the syrange for the particles to move which compacts and forces the seasoning to come out of the syrange, throught the whole time the presure applied the less volume there was and there is n temperature change.

Charles law-constant pressure
Example-the egg lab
Why? because it had constant pressure on the egg and temperature and volume vary directly.

REAL LIFE-Is the hot air balloon . the reason this is hot air ballons use hot or cold air to control going up or down as the heat fills the baloon the particles are moving very rapidly alowing the baloon the rise and then when they put colder air into the ballon it makes those particles slow down and lets the balloon go down

REAL LIFE- Every year i leave my bike in shed during winter and when spring comes around i pull it out of the shed and notice my tires are flat. The reason for this is the charles law since it was cold outdise the molecules inside the bike tire tube would condense more and more and didnt allow them move rapidly like they would in warm weather

Gay-Luzzac's law-constant volume
Example-pipet book lab
Why? because there was constant pressure on the pipet filled with liquid, it had constant volume.
