Question

Which of the following has minimum kinetic energy? a.particles of ice below zero degree celsius b.particles of water at hundred degree celsius c.particles of water at zero degree celsius d.particles of steam at hundresd degree celsius

Answer 1

as per my guess, it's c

Answer 2

Answer:

Option a. Particles of ice below zero degrees. It is the correct option. Particles of ice below zero degrees Celsius will have minimum kinetic energy.

Explanation:

It is because ice is a solid form of water, in which the water molecules are bounded by strong intermolecular forces which decrease the movement of water molecules considerably.

• Particles of water at zero degrees will also have less kinetic energy but slightly more than particles of ice below zero degrees celsius.

• Whereas particles of steam at hundred degrees celsius will have the highest kinetic energy because Steam is the gaseous form of water in which the molecules are far apart from each other, there will be a very large space between the particles of gaseous molecules because of which the force of attraction between them is almost negligible.
• Also, particles of water at hundred degrees celsius will have slightly less kinetic energy than particles of steam.
