Everything is made of tiny particles! Learn to draw and read the diagrams that show how particles are arranged in solids, liquids, and gases.
What you’ll learn
- Everything Is Made of ParticlesUnderstand that matter is made of particles and that particle diagrams show them as circles.Everything is made of tiny particles too small to see. A particle diagram draws them as circles so we can picture how they are arranged. The same particles are packed differently in solids, liquids, and gases.
- How Particles Are ArrangedDescribe how particles are arranged and move in solids, liquids, and gases.In a solid, particles are packed tightly in neat rows and can only wiggle. In a liquid, they are close but loose and can slide past each other. In a gas, they are far apart and zoom about freely. The arrangement explains each state's behaviour.
- Drawing and Reading DiagramsDraw and read particle diagrams to identify the state of matter.To draw a solid, pack circles in a tight, neat grid; a liquid is close but jumbled; a gas is far apart with big gaps. Reading a diagram works the same way in reverse, letting us name the state from the picture of its particles.
Questions this course answers
What is a particle diagram?
A particle diagram draws particles as circles so we can see how they are arranged in each state.
How are the particles arranged in a solid?
In a solid, particles are packed tightly in a neat, ordered pattern and stay in place.
Why can a liquid flow and take the shape of its container?
In a liquid the particles are close but not in neat rows, so they can slide past each other and flow.
In which state are the particles the most spread out?
In a gas the particles are far apart with lots of empty space, more spread out than in solids or liquids.
You see a diagram of circles far apart with big gaps. Which state is it?
Circles far apart with big gaps show a gas, because gas particles have lots of space between them.
When water melts from ice, what happens to its particles?
It is the same particles the whole time; melting just lets them move from a tight grid into a looser, sliding arrangement.
