Detailed explanation-1: -Particles with more kinetic energy move faster and farther apart. Particles with less energy move more slowly and stay closer together.

Detailed explanation-2: -With an increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature.

Detailed explanation-3: -An increase in the motion of the atoms competes with the attraction between atoms and causes them to move a little further apart. Cooling a solid decreases the motion of the atoms. A decrease in the motion of the atoms allows the attractions between atoms to bring them a little close together.

Detailed explanation-4: -As the solid is heated, its particles gain more energy. This makes the particles vibrate faster and they move further apart.

Detailed explanation-5: -In a gas, the particles have very little attraction to each other. They are very far apart compared to the particles in a solid or liquid, and are constantly moving. The particles don’t interact with one another but just hit and bounce off of each other when they collide.
