According to the kinetic theory, particles in matter are in constant motion. In solids, they vibrate in place; in liquids, they move past one another; and in gases, they move freely. The temperature of a substance is a measure of the average kinetic energy of its particles.
Explicación
## Step 1The kinetic theory of matter is a fundamental concept in physics that explains the behavior of particles in different states of matter. According to this theory, all matter is composed of tiny particles, which can be atoms or molecules. These particles are in constant motion, and the speed of this motion is related to the temperature of the substance.## Step 2In solids, the particles are closely packed together and can only vibrate in place. This is why solids have a definite shape and volume.## Step 3In liquids, the particles are still close together but can move past one another. This allows liquids to flow and take the shape of their container.## Step 4In gases, the particles are far apart and move freely. This is why gases can expand to fill any available space.## Step 5The kinetic theory also explains that the temperature of a substance is a measure of the average kinetic energy of its particles. The higher the temperature, the faster the particles are moving.
