According to the kinetic theory of solids (kinetic particle theory) solids, the molecules in a solid vibrate around a fixed location in the solid. The molecules are in a low enough energy state that it requires a lot of additional energy to displace a large number of them simultaneously from their normal neighborhood where they oscillate. The lower the temperature, the smaller the range of their oscillation. Molecules in liquids and gasses are higher energy with much wider range of vibration and no fixed location that they vibrate around, so displacing a bunch of molecules requires much less energy.
Because the molecules in solids are much more closely packed than in gases and strongly resist any significant displacement from their preferred range of oscillation, this manifests as "hardness". Solids that resist displacement less are softer.

What is partical therory?
A scientific theory that explains the properties of solid, liquids and gases, and also that matter are made up of tiny particles. This theory has been out dated by the kinetic molecular theory.
According to the kinetic-molecular theory the atoms of a gas have more energy than what other state of matter?
a solid
Why the inter-particle space increases on heating a solid at its melting point?
when we heat a substance its kinetic energy increases and due to this kinetic energy the force of attraction decreases and can no longer hold the particles together.
What causes melting and boiling in terms of the kinetic molecular theory?
The kinetic theory states that when a solid is heated the bonds between the particles are loosened thus making it a liquid.
What happens to a particle in a solid when it gets cold?
the particle in a solid overcome the strong attraction between them the particle in a solid overcome the strong attraction between them the particle in a solid overcome the strong attraction between them
What is the stages of particle theory?
solid-liquid-gaz
Explanation of vaporization using particle theory?
Vaporization is the transition of matter from solid or liquid to gas. Vaporization of matter occurs when the molecules have sufficient kinetic energy to overcome molecular cohesion.
How do you group materials as solid liquid or gas?
Particle theory
In particle theory why does liquid go to solid?
Closer bonding of particles.
What are the main factys of conduction?
Thermal conduction is the transfer of heat energy through particles in contact with one another. Because heat energy is essentially kinetic energy, the particle with more kinetic energy collides with the particle with less kinetic energy, speeding it up and therefore causing it to absorb some of the heat energy from the first particle.
What is the relationship between temperature and molecular and kinetic energy?
The definition of temperature is the average kinetic energy of a molecule/solid/whatever

According to the kinetic-molecular theory the atoms of a gas have more energy than what other state of matter?
a solid
Is thermal energy conducted through a solid object as kinetic energy?
yup
Explain by kinetic molecular theory why ice is more dense then water vapours?
By looking at the states of matter ( solid ,liquid or gas) we can determine that a giben sample will have how much energy. Molecules in solid have least kinetic energy. Molecules in vapor (gas) have highest kinetic energy. Liquids have moderatee kinetic energy.
Why the inter-particle space increases on heating a solid at its melting point?
when we heat a substance its kinetic energy increases and due to this kinetic energy the force of attraction decreases and can no longer hold the particles together.
What makes sublimation possible?
according to kinectic particle theory the changing of state from solid to gas and gas to solid directly is sublimation eg sodium chloride.
