when the process of photosynthesis takes place then glucose is formed as a product. then , this glucose only is stored in the plants in the form of starch in leaves , stems , etc. parts of the plant. therefore , to determine whether photosynthesis has taken place or not the presence of starch can be tested in a plant by an experiment.
Physical properties can be tested without changing the substance a new substance. Color, density, volume and melting and/or boiling point are examples of physical properties that can be observed and/or tested.
If the leaf is tested for starch using iodine, and the iodine turns blue-black in colour it shows that photosynthesis has taken place.

Benzoylecgonine is the major metabolite that is tested for to determine whether or not cocaine was ingested. Cocaine itself does not stay in the system long enough to be a reliable indication of whether or not someone ingested the drug. Benzoylecgonin can be detected for a much longer period than cocaine.
A hypothesis is tested by an experiment. A hypothesis is an estimate or guess about an outcome. The experiment proves whether the hypothesis is correct or not correct.

The state of the substance, the color of it and the odor (should be careful and keep the distance, otherwise may cause irritations or hazard) can be tested without altering the substance.

If a cake is cooking only on the top, it may be that the oven is set on "broil" instead of on "bake," or that the bottom element of the oven may be broken. Another possibility is that the cake simply has not baked long enough to be "done" throughout. If the oven is set at too high a temperature, the top of the cake might scorch before the interior is baked. The oven temperature… Read More
