I am doing an NVQ in Dispensing can you help me please.
I want to know how you should measure liquids by difference if they are
1, Flammable 2, Colourless 3, viscous 4, Volatile
which one is it.
I am doing an NVQ level 2 dispensing assistant course and the answer is
3, Viscous

∙ 14y ago-Find a constant volume, c. (water is generally used)
-place an item with an unknown volume, x, in the constant, c. The total volume will rise.
-subtract c from (x+c) and you are left with x, or the volume of the unknown
Eureka! ( <-- Archimedes' supposedly shouted this when he discovered the principle)
You found volume by difference.

∙ 7y agoThe volume by difference method may be used for non-porous and non-soluble objects. The initial volume of liquid must be measured and noted, as VL. The object is then totally immersed in the liquid and resulting new volume is measured and noted, as VLO. The object volume, VO , is then given by : VO = VLO - VL .

What is the difference between balance and graduated cylinder?
Balance measures weight. The graduated cyliner measures volume. Think scale and measuring cup.
What is the main advantage of using pipette in measuring the volume of liquid?
The main disadvantage of using a pipet in measuring the volume of a liquid is that you cannot dispense large quantities.
What instrument is used for finding volume?
The main way to establish volume is by measuring the amount of liquid an object displaces. A way to do this is by placing an object in a graduated cylinder of water. The difference between the measurement of volume before and after is equal to the volume of the object.
Are beakers used for measuring?
NO!!! Use a 'Measuring Cylinder' for an exact volume of liquid.
What 2 ways could you find out a volume of a brick?
Submersion method: fill a container and mark its volume. Place the brick in the water. Measure the new level. Calculate the volume difference from before and after. Dimension-measuring method: measure the length, width and depth of the brick, Multiply them together.
How does this measuring volume by difference method compare with measuring volume using math for these odd shaped objects?
cause it is way more simple and it takes way less time
What is the difference between a measuring spoon and a scale?
scale measures force and/or mass; spoon measures volume
Pictures and uses of laboratory equipments?
Beaker - measuring volume of the solution Measuring cylinder - measuring volume
How will you find the volume of stone using measuring cylinder?
The volume of the stone is measured by displacement. Water is put into the measuring cylinder to a noted mark. The stone is placed in the cylinder and the water level will rise. The difference between the two levels is the volume in ml of the stone.
How can you measure your volume?
You can measure your volume by measuring the difference in depth of a known pool of water with you in it and with you out if it. Holding your breath is going to change your volume, so you might need to consider that as well.
What is the difference between specific volume and volume?
Question is not clear...what do you mean?
Is a measuring cylinder is used for volume?
Yes, a measuring cylinder is used for measuring volume. It is called a graduated cylinder
How is volume determined?
By measuring it in a measuring cylinder or beaker or some container of a known volume.
Unit for measuring the volume of sound?
Decibels are the scale used for measuring the volume of sounds.
What do scientists use a graduate for?
You might mean a graduated cylinder, which is used for measuring the volume of liquids.
50ml from a large beaker measured in a measuring cylinder is actually?
A small difference exist because the beaker is not calibrated for volume.
How is liquid volume determined?
By measuring it in a measuring cylinder or beaker or some container of a known volume.
