Weighing by difference is generally more accurate than direct weighing because it accounts for any loss of material during the weighing process. Direct weighing can be influenced by factors like measurement errors or environmental conditions, which may affect the accuracy of the result.

Why do you weigh by difference?
Weighing by difference is a technique used to calculate the weight of a substance by measuring the weight of the container before and after adding the substance. This method helps to eliminate errors caused by the container's weight, ensuring more accurate measurements of the substance.
How does weighing by difference compare to saving pencil shavings and weighing them to see how much was shaved off?
Weighing by difference involves weighing the entire sample before and after the desired component is removed, while saving pencil shavings involves physically collecting and weighing the material removed. Weighing by difference is more accurate as it accounts for any losses that may occur during the process, such as dust. However, saving pencil shavings can provide a visual representation of the amount removed and is more suitable for larger components that are easily collected.
Who invented the first weighing scale?
The first weighing scale is said to have been invented by the ancient Egyptians around 2,000 BC. However, a more modern version of the weighing scale was developed in the 18th century by the French inventor, Richard Salter.
What do mass balances do that weighing scales don't?
Mass balances compare the force of gravity on two masses, while weighing scales use a spring and measure the force of gravity by studying the extension of the spring. A mass balance would give the same answer on the Moon, while the weighing scales would give an answer about a sixth of the correct value.
Why is it necessary to weigh by difference?
Weighing by difference is necessary to accurately determine the amount of the substance being measured, as it accounts for any impurities or moisture that may be present. By subtracting the initial weight of the container from the final weight of the container with the substance, we obtain the weight of the substance itself. This method ensures the measurement is more precise and reliable.

Why do managers consider direct costs to be more accurate then indirect costs?
Answer this question...why do managers cosider direct costs to be more accurate than indirect costs?
Which measurement of body composition is more accurate bmi measurements or percent body fat measurements from hydrostatic weighing?
Bmi
Would using a pipet to determine density be more accurate?
A pipette is quite accurate. So yes weighing the contents of one into a vessel to get the weight (mass) would be an accurate way of measuring density.
The most accurate method of body fat testing is?
Dual Energy X-Ray Absorptiometry is the most accurate method of measuring body fat composition. This method is more commonly referred to as DEXA.Hydrostatic weighing
What is the difference between the oils?
please provide more information with your question in order to get a more accurate answer. Thanks!
What is digital scale?
Digital scale is a electronic weighing devices that integrate with modern sensor technology, electronic technology and computer calculating technology. It is more accurate, more sensible, more convenient than traditional spring scale.
What is a better test for alcohol breath or blood?
Blood is always more accurate as it is a direct test - breath is indirect.
Why are masses in chemistry lab usually determined by a difference method?
Masses are typically determined by a difference method in chemistry labs to minimize errors introduced by other factors, such as variations in weighing equipment or environmental conditions. By measuring the difference in mass before and after a reaction or process, these potential sources of error are canceled out, providing a more accurate measurement of the mass change.
What is the estimated difference?
Please provide more context or details so I can give you an accurate answer.
How much weight do you subtract when weighing yourself with clothes on?
The amount of weight you should subtract when weighing yourself with clothes on can vary depending on the type and heaviness of the clothing. On average, clothing can add anywhere from 1 to 5 pounds to your weight. To get a more accurate measurement, consider weighing yourself without clothes or using a consistent outfit each time you weigh yourself to maintain uniformity.
