Hypothesis: If a fixed amount of gas is heated, then the volume will because the heat will cause the molecules of gas to move faster and further apart

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table

explanation:

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

i think is conclusions.i think so
