How do particles move in a solid?
Particles in a solid are packed closely together in a fixed arrangement. They vibrate around fixed positions but do not move from place to place.
How do particles move in a liquid?
Particles in a liquid are close together but can slide past one another. This allows liquids to flow and take the shape of the bottom of their container.
How do particles move in a gas?
Particles in a gas move rapidly and randomly in all directions. They have high kinetic energy and significant space between them, allowing them to expand to fill any container.
How does energy affect the speed of particle movement?
The speed of movement is directly related to temperature. As thermal energy increases, the kinetic energy (K.E. = \frac{1}{2}mv^2) of the particles increases, causing them to move or vibrate faster.
