A science class breaks into four groups and tests the pH of the soil surrounding the school. Each group goes to an area that is three meters squared (3m2) in size and tests the soil four different times within that square. The data collected is then placed into a table for everyone to see as shown below.
Four students draw the following conclusions from the data
Student 1. Group D's data should be discarded because it is not similar enough to the other groups' data
Student 2: There must be something near the parking lot that causes the pH of the soul to be higher and the class should design a new experiment to determine whether
Student 3. There are definitely more magnesium ions in the soil near the parking lot, and that is why the pH of the soil is higher there
Student 4. The pH of the soil in the ball field should be measured again because no two readings were identical
Which student's conclusion is scientifically valid based on the data in the table above? A. Student 1 B. Student 2 C. student 3 D student 4

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)
