Kinetic Particle Model Of Matter
Muhtasari
Ice, water and steam are all the same substance, yet they behave completely differently: one holds its shape, one flows, one fills the whole room. The difference is not in the particles themselves but in how they are arranged and how they move. The kinetic particle model explains every solid, liquid and gas with one simple picture.
In this lesson you will learn the distinguishing properties of solids, liquids and gases in terms of the arrangement, spacing and motion of their particles, and you will learn the names of the changes of state that carry a substance from one to another, such as melting, boiling, condensation and solidification.
Malengo
- Know the distinguishing properties of solids, liquids and gases
- Know the terms for the changes in state between solids, liquids and gases (gas to solid and solid to gas transfers are not required)

What Is a Fluid?
Matter most commonly exists as a solid, liquid, gas, or plasma; these states are known as the common phases of matter . Solids have a definite shape and a specific volume, liquids have a definite volume but their shape changes depending on the container in which they are held, gases have neither a d

Phase Changes
Up to now, we have considered the behavior of ideal gases. Real gases are like ideal gases at high temperatures. At lower temperatures, however, the interactions between the molecules and their volumes cannot be ignored. The molecules are very close (condensation occurs) and there is a dramatic decr
