Why does the volume of water have to be the same in different containers?
The volume of water must be the same in different containers to ensure a fair and accurate comparison of quantities. If the volumes were different, it would skew the results when evaluating or measuring the water based on volume. Keeping the volume consistent allows for reliable and consistent measurements to be taken.
What is the principle is involved in determining the volume of sand in water?
You can very accurately determine the volume of sand using water. If you just take some sand and measure the volume, a lot of the volume you measure is actually the empty space between the sand crystals. If you want the true volume of the sand, you must use the water method.To do this, start with a known volume of water (use a graduated cylinder for instance). Record this volume. The weigh out a certain amount of sand, and add this sand to the water. When you do that, the volume of the water will increase. Record this new volume. Then simply subtract the initial volume from the final volume. This difference is the volume of the sand particles. You can also calculate the density of sand by this method since you weighed the sand before adding it, and the density is just weight ÷ volume.
What must happen to the volume of a given mass of solid gold when it becomes a liquid?
the volume increases, the same way water takes up more room then ice.
How do you measure volume of irregular objects?
Below is a method you can use when measuring relatively small objects. Firstly, you can pour a known amount of water into a measuring cylinder. Next place the object into the water and ensure that it is completely submerged. Note the increase in the height of the water and its coresponding volume marking. The increase in volume from the original volume of water is the volume of the object. You can use a displacement can instead of a measuring cylinder to make you result more accurate.
How can you find displacement of a metal in 50 mL of water when given the mass?
Place the piece of metal in 50mL of water and subtract the 50mL from the new volume of water. The difference will be the volume of the metal in mL and cm3. Then find the density by dividing the mass by the volume of the metal. The water must completely cover the metal in order for the displacement method of determining the volume to work.
What is the purpose of measuring volume of an area?
to measure volume the object must be three dimensional. the purpose of measuring the volume of an area is to know its capacity

What properties must a solid have for the water displacement method to be useful?
Volume. The displacement method refers to immersing in a liquid. If the liquid is in a container with volume measurement marks, then the object's volume is the difference in the liquid's volume, measured before and after immersion. There's a legend that the discovery of the displacement method was made by Archimedes when entering a bathtub full of water, which overflowed. This is postulated as the source of the exclamation "Eureka!" ("I have found it").
How is the volume of water found?
To find the volume of water you must put it in a graduated cylinder. Read the measurements.
What three measurements must you make when finding the density of a liquid?
Volume of the liquid. The mass of the liquid. The temperature of the liquid ( this can affect the volume). The tare(nett) weight of the containing vessel. The general equatyion for density is density = mass/ volume or D = m/v
WhAT unit would you use to measure water in a pool?
The answer will depend on what quality of the water you wish to measure. Some possibilities are:degrees Celsius (temperature),metres (depth),litres (volume).mm, cm, m [cubed] (volume)Not sure of the units for measuring contamination - I am sure pools must have to monitor that!
Why must the difference between the water level in the eudiometer tube and the water level in the beaker be measured?
The pressure of the gases in the eudiometer tube must equal the atmospheric pressure. If the water levels are not at he same height, then this is not the case. Therefore, in order to account for this difference and get accurate results, you must subtract the water levels and convert to mmHg.
Is volume displacement of a cylinder more accurate than measuring the dimensions?
Volume displacement is a good way to find the volume of a cylinder, and is probably better than simply measuring it. To measure and calculate a cylinder's volume, you must use pi, which is typically rounded to 3.14. Rounding means less accuracy, and there should be no rounding involved in volume displacement.
Can you dilute haircolor developer with water?
It must be distilled water but yes. You can combine equal parts distilled water and 40 volume to get 20 volume developer.
What method used to measure irregular solids?
To measure what quantity of irregular solids? If its volume you are referring then you can use the volume displacement method where you need a measuring cylinder, water and possibly a displacement can.Measure a known quantity of water. Then immerse the irregular solid in this cylinder. The rise in the water level equals the volume of the irregular solid. Note that if the irregular object floats, a sinker must be used to fully immerse the irregular solid, where the volume of the sinker should be known.Hope this helps- if you need more information email me @ physicsisland@hotmail.com
