The value typically calculated from other measurements in the ideal gas law is the unknown variable representing pressure, volume, temperature, or number of moles. By rearranging the equation PV = nRT, you can solve for the unknown variable based on the values of the other variables.

What is the importance of your choice of units in expressing the value of the ideal gas law constant?

If any other units are used, the value will be different. --Depending on the units you chose the value of the constant differs


What does the term true value mean in science?

In classical physics it was thought that every physical quantity has a "true value" that can be only estimated through measurements due to measurements errors. The way of getting nearer and nearer to this "true value" was thought on one side to increase the measurement accuracy, on the other side to increase the number of measurements so to use statistical methods to attenuate the effect of random errors. The situation is completely changed with quantum mechanics. In quantum mechanics an "intrinsic" inaccuracy affects all the physical quantities, independently of measurement errors. Thus physical quantities would be random variables even if measured by an ideal instrument with no bias and no random error. Thus, in modern physics no physical quantity "true value" exists. The only exception is the very rare and particular case of quantum self-state of a certain variable, where that variable only ha a precise value (but not the other variables of the problem !). However this is an extreme and unpractical case, and it seems to me not the case of going in deep in its explanation here.

Why the value of coefficient of contraction is greater then the theoratical value in experiment?

The coefficient of contraction in an experiment may be greater than the theoretical value due to factors such as flow imperfections, wall roughness, or turbulence in the flow. These factors can lead to additional energy losses and create a greater contraction in the flow compared to the ideal theoretical case. Experimental conditions and inaccuracies in measurements can also contribute to discrepancies between the observed and theoretical values of the coefficient of contraction.

precise but unreliable.


What is the difference between the accuracy of measurements and the precision of measurements?

Precision is how close your measurements are. Accuracy is how close your measurements are to the actual measurement.


Why you consider only rms value of voltages and currents in ac circuits?

RMS is most commonly used measurement for AC because the power calculated from it matches the power calculated from DC and is the true power, if there is no phase shift. Its not the only measurement, just the most generally useful. Other measurements are still useful for purposes other than power calculation.


Is it true that Precision is a measure of how close a resulting or measurement is to the accepted value of the quantity being measured?

Precision is a measure of how close repeated measurements are to each other. It does not take into account how close the average of those measurements is to the true or accepted value. Accuracy, on the other hand, is a measure of how close a measurement is to the true or accepted value.


What is the closeness of a set of measurements with each other called?

The closeness of a set of measurements with each other is called precision. Precision refers to the degree to which repeated measurements under unchanged conditions show the same results. It indicates the consistency and reliability of the measurements, regardless of whether they are close to the true value (which relates to accuracy).

Scientists take scientific measurements carefully in order to ensure their reliability and validity. What is the difference between accuracy and precision in scientific measurements a. Accuracy is how?

Accuracy refers to how close a measured value is to the true or accepted value, while precision refers to how close multiple measurements of the same quantity are to each other. In other words, accuracy indicates the correctness of a measurement, while precision indicates the consistency or reproducibility of measurements.


How can estimation help to decide if answer to multiplication problem makes sense?

If the estimated value is very different from the calculated value then the answer is wrong. Unfortunately, it does not work the other way. An estimate can be close to the calculated value but the answer can still be wrong.


What is the difference between accuracy and precision in scientific measurements?

Accuracy refers to how close a measurement is to the true or accepted value, while precision refers to how close repeated measurements are to each other. A measurement can be precise but not accurate if it consistently misses the true value by the same amount. Conversely, a measurement can be accurate but not precise if the measurements are spread out but centered around the true value.


How can we describe these measurements in terms of accuracy and precision?

Accuracy refers to how close the measured value is to the true value, while precision refers to how close the measured values are to each other. A measurement that is both accurate and precise will be close to the true value and have very little variation among repeated measurements. Accuracy can be evaluated by comparing the measured value to a known standard, while precision can be assessed by determining the consistency of repeated measurements.
