200m long.
another name for test tube is culture tube or sample tube
It depends on what size test tube you are using.
If a test tube is clean and dry, then there should be nothing in it.
My best bet would be to heat the test tube to help evaporate the left over water. If for some reason it is a solid, that flush it out with water, then do the first step. The easiest way of drying test tubes would just be by turning it upside down in a test tube holder. Make sure you flush it out with distilled water though to get rid of any residues.
It is used to measure the depth of a small hole in the ground.
You would obtain a test tube, measure the mass of the test tube. Then add the NaCl to the test tube and measure the mass. Then subtract the mass of the test tube from the mass of the test tube+the NaCl to find the mass of the NaCl.
a test tube rock is used to measure liquids
A test tube 13 mm (about half an inch) in diameter and 100 mm (a bit under 4 inches) long.

Scale. :)
that depends on the kind of test tube that you have. if a test tube is calibrated then it measures the volume of a liquid that is placed inside it. if the test tube is non calibrated then its meant for storage and mixing so it does not measure anything..
A small graduated test tube can measure ml.
When heating a test tube, you would use a test tube holder. It can also be used to hold/ support pipettes, etc. http://www.answers.com/mt/test-tube-holder
