2. According to the kinetic theory, how do particles in matter behave? __ Part 2: States of Matter and Particle Behavior

## Step 1<br />The 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.<br /><br />## Step 2<br />In solids, the particles are closely packed together and can only vibrate in place. This is why solids have a definite shape and volume.<br /><br />## Step 3<br />In 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.<br /><br />## Step 4<br />In gases, the particles are far apart and move freely. This is why gases can expand to fill any available space.<br /><br />## Step 5<br />The 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.
