Transcript of Sciency matter stuff.

Solids Particles
The particles that make up a solid are paked
very close together. In addition, each particle
is tightly fixed in one postion. This fixed, closely paked arrangement of particles cause a solid to have a definite shape and volume. Types of solids There are two types of solids Crystalline solids and Amorphous solids. Crystalline soilds have particles that form a regular repeating pattern. Amorphous solids have particles that dont form any regular pattern Changes in a solid Solids to Gas
Sublimination is the change from a solid to a gas without passing through the liquid state. some examples of this are Dry Ice and Gun Powder when mixed with heat. Solids to Liquids
Melting is the change from a solid to a liquid. Melting only happens when enough heat is applied to an object. The melting point and freezing point for an object are the same. Liquids Gases Matter Particles The particles that make up a liquid are paked
very loosely but close together. This lets liquids form to the shape of their container. This loose arrangement of particles cause a liquid to have a definite volume but not shape. Surface Tension is the result of an inward pull among the molecules of a liquid that bring the molecules on the surface closer together.
Viscosity is a liquids resistance to flowing. Properties Changes in a Liquid Liquids to Solids
Freezing is the change from a liquid to a solid. Freezing only happens when an object is cooled enough. The melting point and freezing point for an object are the same. Liquids to Gas
Vapotization is the change from a liquid to a gas.
Boiling and Evaporization are both forms of vaporiztion.
Particles The particles that make up a gas are paked
very loose. This lets gases form to the shape of their container. This loose arrangement of particles cause a gas to not have a definite volume or shape. Properties The volume of a gas fluctuates due to temperature, pressure, and volume.
A change in any one of these can cause the volume to either increase or decrease. Changes in a Gas Gases to Liquids
Condensation is the change from a gas to a liquid. Condenstaion occurs when particles in a gas loose enough thermal energy to form a liquid. Gas Laws
When pressure increases volume decreases.
When temperature increases volume increases.
When volume increases pressure increases.
When pressure decreases volume increases.
When temperature decreases volume decreases.
When volume decreases pressure decreases. Plasma What is it Nuclear fusion is a process in which two atomic nuclei combine, forming a larger nucleus and releasing huge amounts of energy.
Nuclear fusion occurs on a huge scale. Nuclear Fusion Where it happens Nuclear fusion is only found naturally in stars.
Nuclear fusion can be replicated in laboratories with Partial Accelerators. A plasma is a state of matter that consists of a gas-like mixture of free electrons and nuclei of atoms that have been stripped of electrons.
