If you wanted to perform a controlled experiment to test the effect of temperature on the pressure of a bicycle tire, which of the following would be necessary? two identical bicycle tiresone bicycle tire kept at a constant temperatureone bicycle tire that experiences changes in temperaturedifferent amounts of air in each tire

I just took the test the answer is A, B and C

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
