How do particles move in a substance?
All substances are made of particles. The particles are attracted to each other – some more than others. And the particles are constantly moving with what’s called ‘Kinetic Energy’. As temperature increases, this kinetic energy increases so they can move around more.
How are the particles in each state of matter of the same substance different?
Matter in the solid state maintains a fixed volume and shape, with component particles (atoms, molecules or ions) close together and fixed into place. Matter in the liquid state maintains a fixed volume, but has a variable shape that adapts to fit its container. Its particles are still close together but move freely.
Do particles move in all states of matter?
Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around. Liquid matter is made of more loosely packed particles.
How does particle motion change as you go from solids to liquids to gases?
A solid particles will move faster and spread out to become a liquid. In a liquid, the particles flow around each other, but are still touching. The liquid particles will spread out even farther and move faster to become a gas.
Which particles of matter move the fastest?
Because the particles are freer to move around in gases than in solids or liquids, gas particles move the fastest. Like a liquid, a gas flows and takes the shape of its container.
How do particles move in liquids?
In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles.
What influences the motion of particles in liquids?
Motion of Particles in Liquids The particles of a liquid are more closely packed than those of a gas. Therefore, attractions between the particles in a liquid affect the movement of the particles.
In which substance do the particles move the most?
Particles move fastest in gases. They move slowest in solids. Gases have the most thermal energy and solids have the least.
In which state of matter do the particles move least easily?
Solid has most closely packed particles. They are hard to compress. The particles in solid are generally linked to each other through electrostatic forces. They barely move when force is applied (unless it’s brittle).
In which state of matter do the particles spread apart?
gases: No definite volume or shape. The atoms and molecules move freely and spread apart from one another.
