This is a simple essay that covers the basic concepts of physics. The essay is descriptive in layman's terminology and is broken down into distinct sections. When reading the paper, it becomes obvious that this paper is to describe the foundation of physics at a basic level. Beginning with Matter and then continuing on through Kinetic Theory, Kinetic Energy and more, the paper ends with Phase Changes.
The Combined Gas Law
The Combined Gas Law
From the Paper:"Mass can be somewhat confusing as it is so fundamental to matter that it can be difficult to perceive independently. Mass is not weight; but rather weight can be said to be the mass of an object times the force of gravity working on the object (Nave 2005). In a situation with absolutely no gravity, matter would sill occupy space, have mass, and have inertia, but it wouldn't weigh anything. Even without weight, it would still have certain dimensions and a resistance to changing its state of motion (or lack thereof). Perhaps another definition of matter, then, could be 'something with volume and a resistance to changes in motion.'
"The kinetic theory relates to the way gas molecules behave in relation to the density of molecules within a given space--or pressure--and temperature. Based on these factors, the velocity of a gas particle--which by definition floats freely through an area until being deflected by a boundary or another gas particle--is changed, and this change can be predicted with a mathematical formula (Physics.org 2009; Weisstein 2009). Two or more gasses mixed in one container will eventually reach equilibrium of both temperature and velocity, meaning that a smaller particle must move faster than a larger particle, as velocity is a function of both speed and mass (Physics.org 2009). Because of the relationship of volume to a particle's velocity, and the relationship of that velocity to temperature, the more confined a gas is the hotter it becomes. This is how pressure cookers are able to generate so much cooking power compared to mere fire."
