Question

Which of the following has the highest kinetic energy.
A. Particles of ice at $$0^{\circ }C$$.
B. Particles of water at $$0^{\circ }C$$.
C. Particles of water at hundred degree Celsius.
D. Particles of steam at hundred degree Celsius.

Answer 1

Hint: To answer this question, we must first understand what kinetic energy is. Kinetic energy is the energy that an object has as a result of its particle motion. We know that gases have the highest particle movement among the three states of matter: solids, liquids, and gases.

Complete answer:
At 100 degrees Celsius, the most kinetic energy will be found in steam particles. Kinetic energy is the energy that an item holds in itself due to motion. The reason for this is that steam is in the form of gases, and the particles of gases are quite far apart. The distance between gas particles is extremely big. When we heat gas particles, they can move very quickly. As a result, its kinetic energy is at its peak.

So, the correct option is D.

Note: Kinetic energy is linked to molecular movement and freedom. We may compare kinetic energy based on a few parameters, the first of which is the state of matter, which includes solid, liquid, and gas. It is the least for solids and the most for gases.For the same state of matter, the second element is temperature dependency. If the temperature is higher, the kinetic energy is higher. The intermolecular distance and intermolecular force of attraction are the most fundamental principles. When the intermolecular distance is greater, the kinetic energy is greater.
