Answer:
1. Sulphuric acid
2. Car battery acid
3. Washing up liquid
4. Milk of magnesia
5. Metal polish
6. Oven cleaner
Explanation:
Universal paper can determine the pH of a solution. It ranges from dark red (pH 0 - very acidic) to orange/yellow, to green (pH 7 - neutral) to blue, dark blue and purple (pH 14 - very alkaline)
Sulphuric acid has the lowest pH as the universal indicator is red.
The next is car battery acid which is pink - not as acidic as red.
The next is washing up liquid, which is yellow, around pH 3 or 4.
The next is milk of magnesia with light blue, around pH 9 or 10.
Metal polish is dark blue - around pH 11.
Oven cleaner is the darkest, with purple.
a process where the scientists performing the research influence the results, in order to show a certain result
This law (expressed mathematically as E = σT4) states that each gadget with temperatures above absolute zero (0K or -273°C or -459°F) emits radiation at a charge proportional to the fourth energy in their absolute temperature.
Wien's displacement law states that the black body radiation curve for one-of-a-kind temperatures height at a wavelength is inversely proportional to temperature.
Wien's displacement law It states that the better the temperature, the lower the wavelength λmax for which the radiation curve reaches its most. The shift to shorter wavelengths corresponds to photons of better energies. In other phrases, λmax (height wavelength) is inversely proportional to temperature.
Wien's regulation, named after the German Physicist Wilhelm Wien, tells us that gadgets of different temperatures emit spectra that height at distinctive wavelengths. hotter objects emit radiations of shorter wavelengths and for this reason, they seem blue.
Wien's regulation tells us that gadgets of various temperatures emit spectra that top at specific wavelengths. hotter gadgets emit a maximum of their radiation at shorter wavelengths; subsequently, they will seem like bluer. Cooler gadgets emit most of their radiation at longer wavelengths; consequently, they'll appear redder.
