Kinetic Molecular Theory Of Solids, Liquid, Gas And Solids
2) Gases are relatively easy to compress while solids are virtually incompressible because the force of attraction is very weak between the gas entities. This also shows that when they have a weaker attraction the distance between the gas entities are very far apart. In solids the force of attraction is very strong causing the solid entities to be close together or compacted.
3) Gases, Liquid, Solid. The ranking is related to the states force of attraction because in Gases …show more content…
But in solids the force of attraction is very strong causing them to be close together and showing that solids can define shape and volume.
5a) The KMT theory or Kinetic Molecular Theory- is the idea that all substances are composed of entities that are in constant,random motion. This theory was founded by the Scottish scientist Robert Brown (1773-1858) who observed random motion from specks of pollen and was known as the Brownian motion. This shows that when entities are in constant,random motion they would collide with each other and any object in their path.
5b) In Figure 5 this shows how when liquid entities, when they are in a constant and random motion.
This also shows how the liquid entities are in a translation motion that causes them to move through spaces along a linear path. The diagram also show that when the liquid entities are heated they cause them to increase their kinetic energy causing them to change state into a gas(evaporation). When the gas entities are formed they go into the same motion as the liquid entities and that would be translation motion. When the gas entities are up in the atmosphere they follow a linear path in results that gases are in frequent and random collisions with each …show more content…
When the dry ice is a liquid the force of attraction is weaker than solid but when warmed up again the liquid would start to vibrate again and become more excited causing the liquid to boil and making the liquid to become the state of a gas. When the dry ice is a gas the dry ice would follow a translational motion and would have a very weak force of
