Problem: Process: - Coal is mined out of the ground - Coal is pulverized into fine powder - The coal is mixed with hot air - The coal and hot air are blown into a boiler - The coal and hot air burn over a fire - Highly purified water is pumped through pipes in the boiler - The water turns into steam - The steam presses against turbines - The turbines spin - Electricity is produced. suppose "water isnt available" happens, how will it affect LESS heat for the house. Which of the following is the supposed perturbation? - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A: directly impacting a step of the process

Problem: Process: - Water flows into the dishwasher - The dishwasher heats the water - The detergent dispenser opens at the right time - Water is shot through the jets to clean the dishes - The dirty water is drained - More water is sprayed to rinse the dishes - The water is drained again - The air is heated in the dishwasher to dry the dishes. suppose "the dishwasher doesnt run long enough to heat up" happens, how will it affect dishes oils and grease removed easier. Which of the following is the supposed perturbation? - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A: indirectly impacting a step of the process

Problem: Process: - Acid rain is produced by chemicals that reach into the atmosphere - Falls onto the ground - The acid rain starts scouring rocks - Destroys vegetation - The lack of vegetation alters the surrounding environment. suppose more chemicals reach the atmosphere happens, how will it affect LESS damage by acid rain. Which of the following is the supposed perturbation? - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A: directly impacting a step of the process

Problem: Process: - Greenhouse gases are released into the air by human activities - The earth changes energy from the sun into heat - Heat rises from the ground - Greenhouse gas molecules in the atmosphere prevent the heat from going into space - The temperature of the earth increases - The temperature continues to rise and melts the polar ice caps - The temperature rises even faster. suppose stringent standards and regulations are implemented and enforeced by world governments happens, how will it affect the ice caps will melt more quickly. Which of the following is the supposed perturbation? - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A:
indirectly impacting a step of the process
