Answer : The correct value of volume is, 9.16
Explanation :
Accuracy : It is defined as the closeness of a measured value to a standard or known value.
For Example: If the mass of a substance is 50 kg and one person weighed 48 kg and another person weighed 55 kg. Then, the weight measured by first person is more accurate.
Precision : It is defined as the closeness of two or more measurements to each other.
For Example: If you weigh a given substance five times and you get 1.8 kg each time. Then the measurement is said to be precise.
Level of precision is determined by the maximum number of decimal places.
As we know that for the measurement of the volume of liquid in graduated cylinder are shown by placing the graduated cylinder on the flat surface and then view the height of the liquid in the graduated cylinder with the naked eyes directly level with the liquid.
The liquid will tend to curve downward that means this curve is known as the meniscus.
In the case of colored liquid, we are always read the upper meniscus of the liquid for the measurement.
In the case of colorless liquid, we are always read the lower meniscus of the liquid for the measurement.
In the given image, there are 5 division between the 9 and 9.5 and the smallest division is, 0.1. So, the volume of liquid will be, 9 + 0.16 = 9.16
Thus, the correct value of volume is, 9.16
