Damien · Answer 1

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
