A student conducts an experiment to see how music affects plant growth. The student obtains four identical plants. Each one is p
otted in the same type of soil and receives the same amount of sunlight and water each day. Plant A listens to classical music for three hours each day. Plant B listens to rock music for three hours each day. Plant C listens to country music for three hours each day. Plant D does not listen to any music at all. 2. Based on the experiment in the scenario, which visual aid would be most helpful in showing the change in the plants' heights over time?
The simplest and most helpful visual aid for this experiment would be if the student sets rulers of some sort or maybe pieces of wood that are properly marked with certain measuring unite. If they are set right next to each plant, the student will be able to monitor constantly how are the plants growing, and the smaller the measuring unites the better, as the student will be able to monitor the situation in higher detail.
Over time, the plants will most surely develop differently, so the student will have it easier to notice the changes. Considering that it is an experiment in question, the student should use proper measurements and to be able to have detailed numbers for it.
The heat required to completely melt the given substance, platinum, we just have to convert first the given mass in mole and multiply the answer to its molar heat of fusion.. Hf = mass x (1/molar mass) x molar heat of fusion Hf = (85.5 g) x (1 mole/195.08 g) x 4.70 kcal/mol Hf = 2.06 kcal
