Kinetic Molecular Theory Of Gases

The kinetic theory of gases is the study of the microscopic behavior of molecules and the interactions which lead to macroscopic relationships like the ideal gas law. The Kinetic Molecular Theory of Gases begins with five postulates that describe the behavior of molecules in a gas. These postulates are based upon some simple, basic scientific notions, but they also involve some simplying assumptions .
                                                                Postulates

• A gas consists of individual particles in constant and random motion.
• The individual particles have negligible volume.
• The individual particles do not attract or repel one another in any way.
• The pressure of the gas is due entirely to the force of the collisions of the gas particles with the walls of the container.



Galindo, Sarah . Period 3

1.) How many blog posts have you completed this semester ? What grade would you give your self for your blogs ?
I Have completed 7 blogs this semester . I would give myself a C .

2.) Predict your final exam grade and your final semester grade ( average 3 test & blog ) .
I predict my final exam grade will be a d or d+ & my final semester grade will be a d- .

3.) Research fun chemistry. Keeping in mind safety, What would you like to learn next semester ?
Next semeser i would like to do more fun & interesting labs & fun projects .

Energy

Potential energy is the same as stored energy. The "stored" energy is held within the gravitational field. When you lift a heavy object you exert energy which later will become kinetic energy when the object is dropped

Kinetic Energy

                               

The word "kinetic" is derived from the Greek word meaning to move, and the word "energy" is the ability to move. Thus, "kinetic energy" is the energy of motion --it's ability to do work. The faster the body moves the more kinetic energy is produced. The greater the mass and speed of an object the more kinetic energy there will be.

Balancing Chemical Euations



A chemical equation is balanced when the number of atoms of each type on each side of the equation is the same.

Chemical Reaction

A chemical reaction is a process that leads to the transformation of one set of chemical substance to another .Chemical reactions can be either spontaneous requiring no input of energy, or non-spontaneous, typically following the input of some type of energy, such as heat, light or electricity. Classically, chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds,although the general concept of a chemical reaction, in particular the notion of a chemical equation is applicable to transformations of elementary particles

The Law of Conservation of Matter & Mass

In the law of conservation of mass or matter, the mass in a system that is closed will be constant. Matter can never be destroyed .

Water Testing

Murcury , Lead , and Arsenic are bad metals to have in our water . Murcury damages the first cell it touches just instantly , and causes organ disfunction. It also causes weakness, headaches, hunger, vision problems, loss of muscle coordination, anxiety, personality changes, memory loss, irrational thinking, delirium, coma and death.
