Why a loaded test tube floats upright?
Well, isn't that just a happy little accident! When a test tube is loaded with a substance that is less dense than the liquid it is placed in, it creates buoyancy, causing the test tube to float upright. It's like a little dance of balance and harmony in the liquid, creating a peaceful and stable environment for our test tube to float gracefully.
What are test tube clamps and what is it used for?
It is a clamp that holds a test tube -- for instance to hold a test tube while heating it without getting burned. It is made from a thick piece of metal wire that is shaped into a spring-loaded clamp to securely hold a test tube.Note the difference between a test tube clamp, and a test tube rack. A clamp is a way to hold a single test tube while heating the contents inside without actually touching the test tube itself. A rack is instead used to hold many test tubes at once in an upright position. See the Related Questions links below for more information on test tube racks.
Why is a test tube placed in a test tube rack?

Uses of test tube rock?
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.
Why was the test tube held in the flame at a 45 degree angle?
At this angle the biggest "area" of the test tube is covered by the flame. Thus it heats up quickly and evenly. Also, by holding the test tube at 45 degrees away from you, you're less likely to be splashed by anything in the test tube boiling over.
