accuracy in measuring

It is the smallest reading that can be accurately measured while using an instrument or a devic..

By using an appropriate device, we can know the measure of a physical quantity.The accuracy of the reading depends on the device and the person taking the measurement. Therefore, accuracy means the extent upto which a measured value agrees with the ..

Uncertainty in Measurement - When dealing with objects that can be counted, one can always get an exact answer. But while measuring the weight of a person, the volume of milk in a container, the length of a cloth etc. it is not possible to measure them exactly. The dif..

The development of chemistry is based upon the systematic approach of the scientists in carrying out different experiments. Scientific theories, inferences and generalizations are made on the observations recorded. The quantitative information involves the measurement of one or more..

Significant Figures and Measuring Instruments - Let us consider the following entries in a Students' Journal: (a) Weight of a calorimeter = 42 g (measuring instrument used is spring balance) The smallest reading the spring balance can record is 1g. There are 42 of 1 g units of h..

These express the degree of accuracy of measurements. It is a statement which gives number of digits up to which we are sure about their accuracy..

It is the expression of accuracy of a physical quantity. The value in digits, accurately known in a measurement plus one digit that is not certain, is called significant figures. Significant figures is directly proportional to the accuracy of measurement..

It is not possible to measure simultaneously both the position and velocity (or momentum) of a microscopic particle with absolute accuracy or certaint..

The accuracy of a measuring instrument depends upon the least count of the measuring instrument. For example, length of a body that can be measured using a tailor's tape, cannot be beyond the minimum and maximum length of the measuring tape. Least ..
