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
Considering the definition of average kinetic energy, the greatest average kinetic energy per molecule is described as: 1 liter of water at a temperature of 75°C.
Average kinetic energy
Thermal energy is the average kinetic energy (energy related to motion) of a very large set of atoms or molecules. This average kinetic energy depends on the temperature, which is related to the movement of the particles (atoms and molecules) that constitute the substances.
That is, by increasing the temperature of a material, be it a liquid, solid or gas, what is done is to increase the agitation or movement of each of the particles that compose it. Then, the transferred energy is used by atoms or molecules to increase their kinetic energy.
In summary, a body at a low temperature will have less thermal energy than another that is at a higher temperature.
Correct answer
Then, the choice with highest temperature is the correct option: 1 liter of water at a temperature of 75°C.
