Answer:
It organizes all of the elements and it allows you to easily find the groups of elements such as
Group 1 of the periodic table consists of hydrogen and the alkali metals
Group 2 consists of the alkaline metals (batteries!)
Groups 3–12 contain transition metals
Groups 13–16 each contain at least one metalloid
Group 17 contains halogens
Group 18 consists of noble gases which are stable.

Explanation:
Answer:
A. 1 liter of water at temperature 75°C
Explanation:
According to kinetic molecular theory average kinetic energy of molecules are directly proportional to absolute temperature.
the quantity of the sample does't depend on kinetic energy only temperature
does so the choice with highest temperature is the correct choice
∵ 1 liter water at 75°C has highest average kinetic energy per molecule
