Why do different states of issue have different properties? It’s because of distinctions in power at the level that atoms and also molecules, the small particles that consist of matter.

### Energy

Energy is defined as the ability to cause changes in matter. Girlfriend can change energy native one type to an additional when friend lift your arm or take it a step. In every case, energy is supplied to move matter — you. The energy of moving matter is called kinetic energy.

### Kinetic concept of Matter

The corpuscle that consist of matter are also constantly moving. They have actually kinetic energy. The theory that every matter consists of constantly relocating particles is dubbed the kinetic concept of matter. You can learn more about it in ~ the URL below.

### Energy and also States the Matter

Particles of matter of the same substance, such together the same element, room attracted come one another. The force of attraction has tendency to traction the corpuscle closer together. The particles require a many kinetic power to overcome the force of attraction and also move apart. It’s prefer a tug of war between opposing forces. The kinetic power of individual corpuscle is on one side, and also the force of attraction in between different particles is top top the other side. The result of the "war" counts on the state that matter. This is depicted in Figure below and in the animation at this URL: http://www.tutorvista.com/content/physics/physics-i/heat/kinetic-molecular-theory.php.

Kinetic power is necessary to overcome the pressure of attraction between particles the the same substance.

In solids, particles don’t have enough kinetic energy to conquer the pressure of attraction between them. The particles room packed very closely together and also cannot move around. All they deserve to do is vibrate. This describes why solids have a addressed volume and also shape.In liquids, corpuscle have enough kinetic power to partly overcome the force of attraction in between them. They can slide previous one one more but no pull fully apart. This explains why liquids can change shape yet have a resolved volume.In gases, particles have actually a the majority of kinetic energy. Castle can completely overcome the pressure of attraction in between them and also move apart. This defines why gases have actually neither a solved volume no one a fixed shape.
