Why nitrogen give blue colour with sodium fusion test?
When nitrogen is present in a sodium fusion test, it forms sodium azide (NaN3), which upon heating decomposes into sodium, nitrogen gas, and atomic nitrogen. The atomic nitrogen emits blue light when it reacts with the oxygen in the air, giving the characteristic blue color to the flame during the sodium fusion test.
What is the best destructive test for showing lack of side wall fusion with a 25mm thick butt weld?
The best destructive test for showing lack of sidewall fusion in a 25mm thick butt weld is the macro-etch test. This test involves cutting a cross-section of the weld, polishing it, and then etching it with a chemical solution to reveal any internal defects, such as lack of sidewall fusion or incomplete penetration. The macro-etch test provides a clear visual indication of discontinuities within the weld.
Why tongs need to be kept near the top of the test tube?
Because sometimes in a lab,you use different and dangerous type chemicals so if for example,You pour a very chemical that uyou can't touch the test-tube and then you have to use the Tongs just so that you could be safe so I think that it is safe and the best idea to have tongs kept near the top of the test-tubes
The procedure indicates that the amount of time th test tube was kept in th boiling water bath should be minimized why was this necessary?
The procedure indicates that the amount of time the test tube was kept boiling in the water bath should be minimized. The water bath should never be allowed to boil dry.
How is Nuclear fusion used?
Nuclear fusion is used as a potential source of clean and abundant energy in research and experimental reactors, such as ITER. It has the potential to produce electricity with fewer greenhouse gas emissions than fossil fuels, and it generates energy by fusing atomic nuclei together at extremely high temperatures. However, commercial fusion power plants are not yet operational.
What was the first hydrogen fusion explosion?
The first hydrogen fusion explosion occurred during the Trinity test in New Mexico on July 16, 1945. This was the first successful detonation of a nuclear weapon.

Why we use only sodium metal in sodium fusion test?
Sodium metal is used in the sodium fusion test because it has a low melting point, making it easy to work with during the testing process. Additionally, sodium forms soluble compounds with a wide range of elements, allowing for the extraction and identification of various components present in a sample.
What are some famous nuclear bomb explosions?
TrinityHiroshimaNagasakiCrossroads Baker (first underwater)Ivy Mike (first fusion bomb, 90% fission yield)Ivy King (highest yield fission bomb)Castle Bravo (first dry fuel fusion bomb, 90% fission yield)Castle Romeo (test of first deliverable fusion bomb, MK-17)Redwing Zuni (test of first clean fusion bomb)Redwing Navaho (test of clean fusion bomb, only 5% fission yield)Tzar Bomba (highest yield fusion bomb, USSR)etc.
