Process:  - Water is heated - The heated water evaporates - The salt is left behind - The evaporated water condenses on a cold surface - The evaporated water is collected - The process is repeated - More salt is removed from the water.  Perturbation hypothesis: suppose water is available from less sources happens, how will it affect more water condenses on a cold surface.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process:  - The bird picks a tree - The bird collects twigs and other refuse - The bird makes a flat base with twigs - The bird makes sides with twigs and other things - The bird adds softer material to the inside - The nest is done.  Perturbation hypothesis: suppose bird searches for items needed happens, how will it affect LESS or SMALLER nests.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process:  - Coal is loaded into the firebox - The boiler produces steam under high pressure - The steam generated in the boiler flows down into a cylinder - Just ahead of the wheels, pushing a tight-fitting plunger, the piston - The piston is connected to one or more of the locomotive&#x27;s wheels through a kind of arm-elbow-shoulder joint called a crank and connecting rod - As the piston pushes, the crank and connecting rod turn the locomotive&#x27;s wheels and power the train along - An outlet valve opens and the piston pushes the steam back through the cylinder and out up the locomotive&#x27;s chimney -   Perturbation hypothesis: suppose there is a storm happens, how will it affect MORE power produced by the steam engine.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no

Process:  - Aluminium cans are put into a recycling bin - Aluminium cans are then collected and taken to a treatment plant - At the treatment plant the aluminium is sorted and cleaned - Readied for reprocessing - The aluminum cans go through a re-melt process - Turned into molten aluminium - The molten aluminum is made into large blocks called ingots - The ingots are sent to mills and are rolled out into thin sheets - The rolls are ready to be made into new aluminum products.  Perturbation hypothesis: suppose People eat more food from cans happens, how will it affect MORE aluminum cans being recycled.  Does the supposed perturbation have an effect (direct or indirect) on the process?

Ans: yes
