Substances are typically tested through experiments and analysis of their physical and chemical properties. Various techniques, such as spectroscopy, chromatography, and mass spectrometry, can be used to identify and characterize the substance based on its unique properties. Testing can also involve conducting biological assays to evaluate the substance's effects on living organisms.
The chemical structure of a substance, the presence of functional groups, and its reactivity are key factors that determine how a substance will react when combined with other substances. Additionally, factors such as polarity, acidity, and basicity also play a role in interactions between substances.
By observing how it reacts with other substances
water
The substances contained in the pH paper react with the substance to be tested; and this is a chemical reaction.
A scientific explanation for a set of observations that can be tested in ways that support it or reject it is called a hypothesis. A hypothesis is a proposed explanation for a phenomenon that can be tested through experiments or observations to determine its validity.
One can determine if a substance is diamagnetic or paramagnetic by observing its response to a magnetic field. Diamagnetic substances are weakly repelled by magnetic fields, while paramagnetic substances are weakly attracted to magnetic fields. This behavior can be tested using a magnet or a magnetic field detector.
Animals die when they are being tested on because they are having foreign substances put into their bodies. Animals that are tested on also have chemicals put into them. An animals body is not made to handle these chemical and foreign substances.

It is tested to determine if the body is producing antibodies to HIV.
You will have to be tested to determine if you are infected with HIV.
It is a glass tube and it is used to contain substances being tested!

If your pee is sent to a lab for testing, it will depend on what is being tested for. The lab will analyze different substances present in your urine to determine if there are any abnormalities or substances of concern. Whether it is considered "clean" or not will depend on the specific criteria set by the testing facility.
Yes, period products have been tested with water to determine their effectiveness in absorbing liquid.
Usually rats because of our similar blood patterns and reactions to different substances.
