Why is water an exception to the particle model of matter?
Water behaves differently to most other substances because, in its solid state (ice), its particles are less densely packed than in its liquid state. This is why ice floats.
What are limitations to the particle model?
Particle theory can help to explain melting, boiling, freezing and condensing. (HT only) Limitations of the simple model include that there are no forces between the spheres, and that atoms, molecules and ions are not solid spheres.
What do liquid particles not have?
Liquids do not have a fixed shape but they do have a fixed volume. The particles are very close together. Most of the particles touch each other. The particles can move around.
Do all liquids have the same particle arrangement?
Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
Which is the particle model for liquid?
Liquids can flow to fill the container. They cannot be compressed easily. The particles are close together but they can move around….Particle model of matter.

What is wrong with the particle model?
The kinetic theory model assumes that particles collide and bounce off each other. But, in reality, particles often do not simply bounce off each other because they have forces of attraction between them. This affects properties such as melting point .
Which of the following Cannot be compressed?
Answer: Solids are held in fixed positions, they can only vibrate. Because the particles can not move, solids have a definite shape and volume, and can’t flow. Because the particles are already packed closely together, solids can’t easily be compressed.
Which of the following is not a characteristic of liquids?
Liquids have definite volume, but indefinite shape. They are free to form droplets and puddles when they are not inside a container. When a liquid is inside a container, it will take its shape. Unlike gases, a liquid will not change its volume to spread out and completely fill a container.
Which of the following is not the property of liquid?
Detailed Solution. Elasticity is not a property of Liquids. Elasticity – If by applying force on an object, there is some change in its original form and when the force is removed, it comes back to its pre-state, then such an object is called the elastic object and this property is called elasticity.
What do you need to know about the particle model?
The surface tension of the water keeps the droplets as distinct structures. One of the first topics I teach my pupils when they arrive in Year 7 (11 years old) is the particle model. This model states what solids, liquids and gases are, and explains the differences in their behaviour.
Why are particles so close to each other in a liquid?
Particles in a liquid. 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.
Why are particles not able to pass through a table?
You cannot pass through a table because both you and the table are solid. Solids have the least energy of the three traditional states of matter. The particles are arranged into a regular pattern (think army ranks) with very little space between the particles.
