Well, honey, the weight of an empty test tube depends on the material it's made of. On average, a glass test tube weighs around 5-10 grams, while a plastic one weighs about 1-2 grams. But hey, if you're really curious, just grab a scale and find out for yourself - it's not rocket science!
A test tube 13 mm (about half an inch) in diameter and 100 mm (a bit under 4 inches) long.
Ya... In a test tube add some aluminum foils and some amount of NaOH... Introduce the flame near mouth of the test tube... Then see the magic...
Test tube racks are commonly used in laboratories to hold and organize multiple test tubes in an upright position for easy observation and handling during experiments. They are also used for storage and transport of samples, ensuring they remain organized and protected. Additionally, test tube racks can be used in educational settings to demonstrate chemical reactions or biological experiments to students.
Since centrifuges spin very rapidly it is important that when placing something in one side to balance it with an equal mass on the opposite side. This weight usually consists of a test tube or microcentrifuge tube that is filled with water or whatever solvent is being used. A roughly equal mass can usually be obtained by pouring a similar volume of the solvent being used into the same type of container. For ultracentrifugation and larger samples it is important to match up masses accurately using a scale. If the centrifuge is not balanced when started it could cause it to wobble and potentially cause damage to the machine or it's surroundings.
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..

It depends on what is inside the test tube. If the test tube is empty nothing will happen, if there is petrol in the test tube the petrol will ignite.

the test tube has air inside it.In the outer surface of the test tube is water.Due to the different media across the test tube surface the reflection of light occurs through the glass surface.Hence the test tube shines(behaves)like a mirror
its obvious that the chemical reaction of the match sets the stick of wood on fire but if you put it in a test tube full of water it will reach its full potential of burning and simply go out the is written by Jesse page
First we measure the test tube on the weight machine and note it . let the wieght be 'a' grams. After that keep putting the salt in the tube until the weight of the test tube ,with salt in it, is = (a + 60) grams . If u accomplish this that means that the salt in the tube is exactly of 60 grams :) .
When finding the mass of air, you need to have a test tube and a stopper. Measure the mass of the test tube and the stopper together. Then, make sure that the air gets in the the tube and put the stopper on. Recheck the mass of the air, test tube, and stopper and subtract just the tube and stopper from the newly recorded mass to find the mass of air.

Light a splint on fire, and then blow the flame out. You want your splint to be glowing red. Then, simply put the splint into the mouth of the the test tube, and if your splint re-lights up into a flame, you'll know it's oxygen gas.
