Which of the following is NOT a characteristic of particles of matter?
Particles of matter are static.
Particles of matter have space between them.
Particles of matter are continuously moving.
Particles of matter attract each other.
Particles of matter are static.
The correct answer is Option A. Particles of matter are not static; rather, they are in a state of continuous random motion and possess kinetic energy.
The correct answer is Option A. Particles of matter are not static; rather, they are in a state of continuous random motion and possess kinetic energy.
Think of people in a crowded room or children playing in a playgroundтАФthey are constantly moving around, colliding, and shifting positions, just like particles in matter.
Space, Motion, Attraction (SMA) тАФ the three main characteristics of particles of matter.
EkтАЛ=21тАЛmv2 тАФ Kinetic energy of particles related to their motion and velocity
vтИЭTтАЛ тАФ Root mean square velocity of particles is proportional to absolute temperature T
According to the kinetic theory of matter, all matter is made up of particles that are constantly in motion. As temperature increases, the kinetic energy of these particles increases, leading to faster movement. Therefore, stating that particles are static contradicts the fundamental behavior of matter.
Particles of matter are extremely small.
Particles of matter have spaces between them.
Particles of matter are continuously moving (possess kinetic energy).
Particles of matter attract each other.
Diffusion of gases and liquids (e.g., smell of perfume spreading)
Brownian motion in microscopic particles
Dissolution of solids in liquids
Option A is incorrect because particles of matter are never static; they vibrate, rotate, or translate depending on the state of matter.
Options B, C, and D are valid characteristics of matter taught in fundamental chemistry.
A is correct тАФ Particles of matter are not static; they are in continuous random motion with kinetic energy.
Always remember that temperature is a direct measure of the average kinetic energy of the particles in a system. When temperature rises, particle motion increases.
