Kinetic theory of solid Those solid particles are closely packed and strongly tied by forces between them. This condition makes the volume of the solid unable to be compressed into smaller volume. Those particles can make their nearest particles to vibrate, but they do not have sufficient energy to release them from the tie. Partikel –partikel zat padat sangat berdekatan dan berikatan kuat oleh gaya antara partikel. Kondisi ini membuat volume zat padat tidak mampu untuk dimampatkan ke dalam volume lebih kecil. Partikel ini dapat membuat getaran partikel berdekatan, tetapi tidak mempunyai energi cukup untuk melepaskannya dari ikatan.

In solid model, the particles are connected by a series of imaginary spring. Those springs enable each particle to vibrate. Model zat padat, partikel-partikel dihubungkan oleh rangkaian gambar pegas. Pegas-pegas ini memungkinkan setiap partikel bergetar

Crystal Solid Most solid particles are orderly and periodically structured. This kind of solid is called crystal. A different kind of solid has different crystal structure, too. Example: salt crystals are in the form of small cubes. Ice is a water crystal which has hexagonal shape. Natrium Chlorine Sebagian besar partikel-partikel zat padat teratur dan tersusun secara periodik. Semacam ini zat padat disebut Crystal. Perbedaan semacam ini mempunyai perbedaan struktur kristal, juga.

Non-Crystal Solid Some materials, such as glasses, plastics, and candles look like solid but not crystal. Those materials are called amorphous solid. The word a morph means having no shape. Many scientists believe that some non crystal materials should be categorized into strong or thick liquid. Beberapa zat, seperti kacamata, plastik, dan lilin tidak kelihatan seperti padat tetapi kristal. Zat itu disebut Amorphous. Kata Amorph artinya tidak punya bentuk. Banyak ilmuwan percaya bahwa beberapa zat non kristal material harus digolongkan ke dalam cairan tebal atau kuat.

Kinetic theory of Liquid The liquid particles are close to each other but they have sufficient energy to move and roam. Partikel-partikel zat cair adalah berdekatan tetapi mereka mempunyai energi cukup untuk pindah dan berjauhan.

Kinetic theory of Gas Based on the kinetic theory of matter, gas particles have sufficient energy to separate themselves from other particles. Therefore, those gas particles are free to move to any directions until they spread out evenly to fill the container. Since those particles are not close to each other, they can be compressed into smaller space. Berdasarkan pada teori kinetik zat, Partikel gas mempunyai energi cukup untuk memisahkan diri dari partikel lainnya. Oleh karena itu, partikel-partikel gas itu bebas untuk bergerak ke manapun arah sampai mereka menyebar untuk mengisi wadahnya. Sejak itu partikel-partikel tidak dekat dengan yang lainnya, mereka dapat dimampatkan ke dalam ruangan yang yang lebih kecil.

Conclusion The energy of the particle is different for each state of matter a. Gas b. Liquid c. Solid (a) In gas, the particles have sufficient energy to oppose the attracting force. (b) The particles which compose liquid do not have sufficient energy to oppose the attracting force, but they have sufficient energy to move and roam. (c) Solid is composed of particles which do not have sufficient energy to roam. Di dalam gas, partikel-partikel memiliki energi yang cukup untuk gaya tarik berlawanan, b. Partikel-partikel susunan zat cair tidak memiliki energi yang cukup untuk gaya tarik berlawanan, tetapi mereka mempunyai energi yang cukup untuk berpindah dan berjauhan. c. Zat padat tersusun partikel-partikel yang tidak mempunyai energi yang cukup untuk berjauhan.

Very close together Fixed, in regular pattern Close together Not arranged in a regular pattern Very far apart Not arranged at all Very small small Very big Vibrate about in their fixed position (cannot move freely) Can move freely. Move randomly, passing and colliding into each other Can move freely Move randomly and colliding into each other at high speeds
