To calculate the volume of a test tube, you need to use the formula for the volume of a cylinder: V = πr^2h. Given the dimensions of the test tube (diameter = 20mm and height = 150mm), first, you need to convert the diameter to radius by dividing by 2 (r = 10mm), then plug the values into the formula to find the volume.

How do you find the volume of water in a beaker?
7.6 ml
What is the SI unit for test tube liquid volume?
Millilitres.
What is 1ml in a test tube?
1 mL in a test tube would be equivalent to filling the test tube up to the 1 mL mark on its scale, representing a volume of 1 milliliter of liquid. Test tubes are used to hold and manipulate small amounts of liquids for various laboratory experiments and procedures.
What is the source of error when using a test tube?
A test tube (or sample tube) has no errors.
What can a test tube be held upright with?
A test tube can be held upright using a test tube rack, a test tube holder, or a clamp attached to a stand. These tools provide stability and prevent the test tube from tipping over during experiments.
How do you calculate weight of 20mm square tube?
weight of ms hollow bar 20mm*20mm
What is the name of the test tube that measures?
A graduated cylinder is a type of test tube that measures volume with markings along its side.
How can a half test tube of sugar and a half test tube of water add up to one full test tube?
When sugar dissolves in water, it occupies space within the water molecules, leading to an increase in volume. So, if you dissolve a half test tube of sugar into a half test tube of water, the volume of the mixture will be greater than the sum of the individual volumes of sugar and water, resulting in a full test tube.
How do you find the volume of water in a beaker?
7.6 ml
What is the volume of 13 x 100mm test tube?
13 ml
If I have a typical test tube shape that is 31mm in diameter and 204mm in total length what is the volume and how do you calculate it?
Volume of a cylinder (the test tube) = pi*radius2*height or length Volume = pi*15.52*204 = 49011*pi cubic mm
What is a 13x100 test tube and its use?
13x100 test tubes are excellent when you need to have larger volume in a test tube. These larger tubes allow more air to touch the sample.
Can be used to hold liquid chemicals but cant measure volume?
a test tube is the answer
What is the size and volume of a small clean test tube?
A small clean test tube typically has a size of about 13mm in diameter and 100mm in length, with a volume capacity of around 10-15 milliliters.
What color tube for cldag test?
A lavender-top tube (EDTA) is typically used for the Complete Blood Count (CBC) test, which includes the measurement of cell volume and numbers.
What does a test tube measure?
A test tube is a container used for holding, mixing, or heating small amounts of liquid during experiments or chemical reactions. It does not measure anything on its own, but is a versatile tool in laboratories for conducting various tests and analyses.
