Measurement is usually defined as the assignment of numbers for objects in question
two students obtain different values for the same measured objects due to several reason
The most probable reason is that since it was merely measurement may be different units or values for same object are given hence the result will be different
Or it depends on what they are measuring. e.g in volumetric measurement it may be due to indeterminate error due to faulty grading of the burette or pipette
why could two students obtain different values for the same measured objects?
Two objects of different masses are suspended from two springs that have the same spring constant. The heavier of the two objects will extend its spring farther beyond the equilibrium point. Why? (4.7) mm
Several groups of general chemistry lab students measured the equilibrium constant for the same chemical equilibrium. In comparing their results, they found that they had different values because the temperatures of the experiments were different. Everyone was disappointed by the inconsistency, except for Dexter when he realized the measurements were made at different measured temperatures: "My esteemed colleagues," he said, "together we have sufficient data to determine two additional thermodynamic parameters and show the lab instructor what we know!" What...
Which statement is wrong? 1. Adding the same amount of heat to two A different objects will produce the same in- in crease in temperature. T 2. Temperature measures the average ki- netic energy of random motion, but not other kinds of energy. 3. Different substances have different ther- A mal properties due to differences in the way 11 energy is stored internally in the substances. 4. When the same amount of heat produces different changes in temperature in two...
4. Students measured the concentration of HCl in a solution by titrating with different indicators to find the end point Indicator Number of measurements Mean HCl concentration (M) (standard deviation) 0.08861 +0.00253 21 Bromothymol Blue Methyl red 0.08476 +0.00165 31 Is there a significant difference (within 95% confidence level of the means obtained through the two indicators or could your reject the null hypothesis? (10 points)
Two objects of different material have the same mass and temperature. When adding them equal amount of heat, the final temperature of each one can be different since they have different? Specific heat Density Expansion Coefficient Thermal conductivity Volume
Fourteen different second-year medical students at a hospital measured the blood pressure of the same person. The systolic readings (mm Hg) are listed below. Use the given data to construct a boxplot and identify the 5-number summary 140 121 135 143 120 125 131 The 5-number summary isndall n mm Hg. 130 120 144 123 140 141 150 (Use ascending order. Type integers or decimals. Do not round.)
Six different second-year medical students at Bellevue Hospital measured the blood pressure of the same person. The systolic readings (in mmHg) are listed below. Find the range, variance, and standard deviation for the given sample data. If the subject's blood pressure remains constant and the medical students correctly apply the same measurement technique, what should be the value of the standard deviation? 143 126 149 137 143 130 Sample variance=____mmHg^2 (Round to the nearest tenth as needed.) Sample standard deviation=___mmHg...
What happens when two objects are in thermal equilibrium? A. The two objects reach the average of their two temperatures. B. The two objects contain the same number of atoms but have different temperatures. C. The temperatures of the two objects have stopped changing even though they are at different temperatures. D. Heat no longer flows between the two objects when they are both at the same temperature.
