Astudent conducted an experiment to test whether talking to plants would them to grow faster. the student talked to one group of plants and hand watered them. the student did not talk to the other group of plants and used sprinklers. after three weeks, the plants that were spoken to showed much more growth than the plants that were not. based on the results of this experiment, which is the best conclusion?

from this experiment, we conclude that hand watering plants are better than watering by sprinklers.

manual watering is the easiest way to water your plants and potted flowers. it requires very little equipment because a simple watering can or a garden hose to which is attached a gun or a spray nozzle is enough. be careful, however, because the main disadvantage of this type of watering is that it is uneconomical and it is impossible to know if the plant has been sufficiently watered.

with sprinklers, the chore of manual watering is over. as a bonus, it reduces the amount of water used and therefore reduces your bill. placed on the ground, flying, fixed or buried.

the best conclusion based on the result of experiment is that the student who talked to one group of plants and hand watered them showed much more growth because they were hand watered not because student talked to them.the hand watered plants had a better growth because they had an adequate amount of water supply needed for their growth.the water reaches upto 6-10 inches.once the water is not soaked by soil the location of water can be shifted.but if you use sprinklers that is not manual then the adequate water supply cannot be fulfilled.there are many regions left where the water does not reach because of sprinklers and sometimes there is water logging that contributes to death of the plant.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
