|
Water molecules have the greatest kinetic energy in
|
|
Ice at 0
|
|
|
Water at 90
|
|
|
Water at 373 K
|
|
|
Steam at 150
|
Explanation:
Detailed explanation-1: -At 100 degrees Celsius, the most kinetic energy will be found in steam particles.
Detailed explanation-2: -The average kinetic energy of the atoms and/or molecules increases, roughly, in proportion to the absolute temperature: [eq] As the temperature increases, the diffusivity increases. Therefore, the water molecules of the hot water have more kinetic energy than the cold ones, and they oscillate more rapidly.
Detailed explanation-3: -Option(A)-Kinetic energy of steam is lesser than water: As steam possesses latent heat of vaporization, it has more kinetic energy than water.
