Question

how would you describe the kinetic energy of the particles in a solid?

high kinetic energy
same kinetic energy as a plasma
low kinetic energy
varying kinetic energy

Explanation:

Analyze particle motion in solids

According to the Kinetic Molecular Theory, the kinetic energy of particles is directly related to temperature and the state of matter. In a solid, particles are tightly packed in a fixed, orderly arrangement. They do not have enough thermal energy to overcome intermolecular attractions and move freely; instead, they only vibrate in fixed positions.

Compare kinetic energy levels

Because the particles in a solid are restricted to vibrational motion, they possess the lowest kinetic energy compared to the liquid, gas, and plasma states of the same substance. Therefore, the kinetic energy of particles in a solid is described as low.

Answer:

• high kinetic energy
• same kinetic energy as a plasma
• low kinetic energy (Correct answer)
• varying kinetic energy
