What Is The Particle Model?
How Does It Relate To Solids, Liquids and gases
Particles in solids are held together very closely. This makes them very strong and difficult to break apart. Solids can also hold their own shape. The particles don’t move around very much but simply vibrate in their spot
Particles in liquids are quite close to each other, however they can move past each other very easily. This makes liquids very easy to break apart and why they cannot hold their own shape, but instead take the shape of their container. The particles in liquids move around quite a bit, bumping gently past each other.
Particles in gases move around very quickly with a lot of space between them, this means you can compress them very easily. Gases don’t just take the shape of their container they fill the space of the container that they are in
What Is Conduction And Convection?
Heat is conducted from a hot end of an object to the cold end. The atoms are packed close and vibrate, so the hotter the metal, the more energy these vibrations have. This energy is transferred from hot parts to cooler parts.
convection occurs when particles with a lot of heat energy move to particles with less.
