Which method of calculating volume is more accurate?

A graduated cylinder should be more accurate than a beaker.

Is water displacement more accurate than calculating volume?

Since you must measure difference between two measurements, your potential error is doubled. Device to measure volume of water is usually a graduated cylinder, and are accurate to about 0.2\% of the volume you are measuring.

What is the most accurate way to measure the volume of a liquid?

Volumetric flasks, burets and pipets are the most accurate with tolerances of less than 0.2\%. To achieve these accuracies the person using the device needs to use the proper technique and the measurements need to made at the temperature for which the glassware was calibrated (usually 20 degrees C).

Which method for finding density was the most accurate?

Graduated Cylinder. The most accurate way to determine an object’s volume, especially in the case of an irregularly shaped object, is to immerse it in water and measure the amount of water it displaces. …

Is volume by displacement accurate?

Displacement measurements will always work. It’s easily the most accurate method because pure calculations require physical dimensional measurements, which might have a visible error.

What is the most accurate way to measure volume in a graduated cylinder?

Place the graduated cylinder on a flat surface and view the height of the liquid in the cylinder with your eyes directly level with the liquid. The liquid will tend to curve downward. This curve is called the meniscus. Always read the measurement at the bottom of the meniscus.

Why is water displacement accurate?

A solid that is more dense than water will sink and displace a volume of liquid equal to the volume of the solid object. Such a volume measurement is typically made in mL. For example, if a substance has a density of 1.23 g/mL and you measure its density to be 1.24 g/mL, then you were accurate.

Which is the most accurate method for measuring volumes of liquids a beaker or a graduated cylinder?

Both graduated cylinders and beakers are pieces of laboratory glassware that have a specific function. Graduated cylinders typically are more accurate at reading the volumes of the liquid inside. Beakers are better for stirring and mixing liquids.

How do you find the accurate density?

Calculating Density After the mass and volume of the solid or liquid have been measured, divide the mass by the volume to calculate the density.

Why is the water displacement method more accurate than measuring?

The change in water level equals the volume of the submerged object. This method is more accurate than measuring water that has spilled out an overflowing beaker. You may need to remind students of the need for accuracy, not only in the weighing of the objects, but also in measuring the volume of displaced water.

Why displacement method determines the volume of an object?

Volume is a measure of the amount of space an object takes up. When a cylinder is submerged in the water it pushes water out of the way. If you measure the amount the water level increases, you can find the volume of the water pushed out of the way.
