The 'pop' test.
To test for hydrogen , have a sample in an upturned boiling/test tube, hydrogen is lighter that air, put a lighted splint/taper to the mouth and it will 'pop'
This is the classic hydrogen test.
An idea that explains something could be called a theory. Good scientific theories are falsifiable which means you could prove it to be false. You can never prove a theory to be true, you can only provide evidence that supports the theory.
The opposite of "prove" is "disprove." While to prove something means to establish its truth or validity through evidence or argument, to disprove means to demonstrate that something is false or invalid. Another related term could be "refute," which involves providing counterarguments or evidence that contradicts a claim.
To prove something you need proof, and proof is defined as ,"any factual evidence that helps to establish the truth of something", and evidence is an actual visual thing, and if you have NOTHING that is visual of and actual object, you cannot prove it, so no.
There are many reasons why you would want or need to flash a bio. You could do this to prove something.
An example of something that could prove one version of what happened is an eyewitness account or testimony. Eyewitnesses can provide firsthand information about an event, offering a specific perspective on what occurred. This can be valuable evidence in understanding a situation or verifying a particular account of events.

Take a sample of the gas in a test tube. Place a lighted splint/taper to it. If it 'pops' , then it is hydrogen. This is the classic hydrogen test. NB When testing for hydrogen keep the test/boiling tube upside down because hydrogen being a lighter gas than air will remain in the tube.
It means to try something out; to taste something; or to prove something.
if it has mass
A Hypothesis is something that you set out to test to prove or disprove. A Lemma is something that has already been proved that you use to help prove something else.
''prove that someone or something is false.''
You can use a lit splint and hold it over where you think the hydrogen is, and if you hear a loud squeaky pop sound it will prove the existence of hydrogen there. You can also test of hydrogen using a Hydrogen Leak Detector.
