Which is more accurate direct weighing or weighing by difference?
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.
How heavy is a weighing scale?
A weighing scale itself is not heavy, as it is designed to be easily movable and transportable. The weight of a weighing scale can vary depending on the type and size, but typically they are lightweight and can be easily carried by hand.
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.
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.
How do you read Weighing scale?
To read a weighing scale, simply step on it and wait for the display to stabilize. The number shown on the display is your current weight.
What is the purpose of a weighing bottle?
A weighing bottle is used to accurately weigh small quantities of solid substances. It helps prevent contamination or loss of material during the weighing process.
Why the sodium hydroxide is weighing in a weighing bottle and not on a piece of filter paper?
Sodium hydroxide is hygroscopic, meaning it readily absorbs moisture from the air. Weighing it in a weighing bottle helps to minimize exposure to moisture and maintain the accuracy of the measurement. Filter paper is porous and can introduce variability in the weight due to moisture absorption.
What does net content of a soft drink mean?
Net content of soft drink means the volume of soft drink present in container. It can be measured by first weighing the filled bottle(W1) followed by weighing of empty and dry bottle(W2). Also measure the density of liquid & multiply it with W1-W2. The result is your net content.
Which one holds more a 2-liter bottle of guava juice or 5 cans of guava juice?
Definitely the 2 liter bottle. Because if your weighing up with the binary number system part 320h in guava juice is odd so it has to be the 2 liter bottle.
Who invented density bottle?
The density bottle was invented by the Irish scientist and mathematician Lord Kelvin, also known as William Thomson, in the 19th century. He developed this apparatus to accurately measure the density of liquids and solids by weighing them.
Can all blood in your body fit in a 2 liter bottle?
All of the blood in and adults body cannot fit in a 2 litre bottle. The average person weighing between 150-180 lbs has 4-5 litres of blood so it is obvious that a 2 litre bottle will not hold that volume of blood.
What would you use to remove 0.25 gram of a solid material from a reagant bottle?
You could use a spatula or a weighing paper to carefully scoop out and collect the 0.25 grams of solid material from the reagent bottle. Be sure to handle the material gently and avoid spilling or contaminating it.
How was teflon originally made?
By accident. A chemist working for DuPont was trying to make something out of tetrafluoroethylene gas, when suddenly the bottle he was using stopped working despite still weighing rather more than an empty bottle. He got curious and cut the bottle open to see what was inside, and found a white waxy substance coating the inside which turned out to be Teflon.
Steps for weighing an object?
Obtain an appropriate weighing device. Make sure the device is calibrated properly. Perform the weighing by placing the object on top of the weighing device.
Is it said weighing a cake or scaling a cake?

Which is more accurate direct weighing or weighing by difference?

How do i know if i used 2.6oz of 6.4 oz if i cant see in the bottle?
If you cannot see inside the bottle you can measure the amount of product you used by using a digital kitchen scale. Start by weighing the bottle before use and noting the weight. After using the product weigh the bottle again and subtract the original weight from the new weight. The difference between the two weights is the amount of product you used. For example if the bottle weighed 6.4 oz before use and 4.8 oz after use the difference is 1.6 oz meaning you used 2.6 oz of product.
