Characteristics of Gases Section 10-1 The Kinetic-Molecular Theory of Matter Prerequisites The kinetic-molecular theory is based on the idea that particles of matter are always in motion. The theory can be used to explain the properties of solids‚ liquids‚ and gases in terms of the energy of particles and the forces that act between them. ideal gas: an imaginary gas that perfectly fits all the assumption of the kinetic-molecular theory.

There are few studies that have looked at male university sport and exercise science students bilateral difference of the hamstrings and quadriceps at 60˚s and 180˚s.The purpose of the study was to look at injury and performance of the hamstrings and quadriceps at 60˚s and 180˚s on the dominant and non-dominant side. Looking at the hamstring to quadriceps muscular ratio (H/Q%)‚ average peak torque‚ average peak torque to body mass ratio (PT/BM) and average power. The study uses 12 participants

Introduction Chemical Kinetics‚ described as the study of rate of chemical processes‚ varies on many factors to determine the time needed for a reaction to complete. The rate of reaction of a chemical reaction is important‚ as reactions are of little use if the time period needed for the reaction to occur is too lengthy. Many factors influence the rate of a chemical reaction‚ such as temperature‚ concentration and surface area. The order of the reaction is based on the concentration of the reactants

A hypo-kinetic disease is a disease that is associated with a lack of physical activity or lack of exercising. Obesity is an example of a hypo-kinetic disease‚ which makes sense because it is a condition of an accumulation of excessive body fat as a result of not creating a caloric deficit as well as not being physically active. Obesity affects the body by changing the normal body composition. It affects cardio-respiratory endurance‚ flexibility‚ muscle endurance and how much power and strength one

In this essay‚ it will be discussed how the Kinetic Molecular Theory explains many gas law specifically Boyle’s gas law‚ Charles’ gas law‚ and Avogadro’s gas law. To understand what will be talked about is to first know what the Kinetic Molecular Theory is. In our textbook is says it is “A simple model for gases that predicts the behavior of most gases under many conditions.” First off‚ we will take a look at Boyle’s Law. As stated in our lab manual “at constant temperature the pressure which a given

Abstract The “Chemical Kinetics” experiment was done to investigate the changes in the rate of reaction under the effect of concentration‚ temperature‚ and presence of a catalyst. It was determined that as the concentration of reactants and the temperature increases‚ the rate of the reaction increases as well. Also‚ the reaction was run by the presence of catalyst‚ and the rate of the reaction increased drastically in the presence of it. The order of the reaction with respect to each reactant

KINETICS OF THE ACID DECOMPOSITION OF THIOSULFATE Aqueous solutions of thiosulfate‚ S2O32-(aq) are stable if neutral or basic‚ but decompose quickly when the thiosulfate is dissolved in acid according to the equation: Sulfur dioxide is a gas at room temperature‚ but is very soluble in water. Sulfur‚ a water insoluble solid‚ forms a colloidal suspension. As a result‚ the solution first becomes cloudy and then opaque. We can take advantage of the developing opacity of the reaction system to do a
