Use the postulates of the kinetic theory to explain the following: i)Matter can exist in three states ii)The pressure exerted by a confined gas decreases as its temperature is lowered iii)A gas of low molecular mass will diffuse through air faster than a gas of high molecular masseven though both are at same temperature. The Kinetic Theory can be used to describe the three physical states of matter namely‚ solid‚ liquid and gas. In this theory‚ some basic assumptions has to be made: a) all matter

one of the most important tools for the accurate determination of molecular structure. Vibration spectroscopy also plays an important role in environmental chemistry. For example‚ the albedo of the earth’s atmosphere is controlled by the absorption of infra-red light by green house gasses‚ which include CO2‚ H2O‚ and CH4. For normal modes that have a changing dipole moment‚ the vibrational spectrum of a molecule is observable using infrared absorption. Such modes are said to be IR active. Raman spectroscopy

MOLECULAR DETECTION OF FUNGAL DISEASES INTRODUCTION With the rise of many new diseases caused due to viruses‚ bacteria and fungi; it is essential for the rapid detection of such diseases. The severity of such diseases can be reduced by its rapid detection carried out by different methods. The conventional methods may include the idea of just identifying the disease symptoms‚ identification of these pathogens in the laboratory by different morphological and biochemical tests‚ etc [1]. The conventional

Item A: Venkatesh was a student at the University of Chicago in 1989 when he became interested in the housing projects surrounding the university where 27‚000 people lived. He approached a group of Black youths hanging around a stairwell in one of the project buildings but instead of answering his carefully prepared questions he found himself held

Claire Kerns Bio Per.1 2-13-13 Cancer reflection Is cancer a disease due to genetics or environment? Cancer is a disease both caused by genetics and environmental factors. Each person has either proto-oncogenes or oncogenes. These are the genes that are responsible for regulating cell division. When a person has an oncogene it is a mutation of a proto-oncogene. The oncogene (dominant gene) tells the cell to continuously divide. This can be a problem if the cell is cancerous. Cancer cells

MOLECULAR BIOLOGIST Education/Training Required: All molecular biologists must at least earn a bachelor’s degree in a related science field. Required courses usually include cell biology‚ evolutionary biology‚ genetics‚ ecology‚ general chemistry‚ biochemistry‚ organic chemistry‚ physics‚ molecular biology‚ multivariable calculus‚ and linear algebra. Most jobs for molecular biologists require a doctoral degree. During college‚ students may want to participate in science-related activities

1) Research Problem What is Molecular Gastronomy? Best described by Hervé This‚ as the understanding of food apart from the chemistry and physics behind the preparations of any dish for example‚ why a mayonnaise becomes firm or why a soufflé swells. So‚ how can chemistry and physics lead to a new ways of cooking? One example quoted by Herve is the egg. If we heat an egg‚ water evaporates‚ the proteins denature and polymerize to enclose water‚ and the end result is a cooked egg. Alternatively

7.6 Summary 1. 7.6 Molecular Orbital Theory a. Intro i. Molecular orbital theory states that the atomic orbitals involved in bonding actually combine to form new orbitals that are the property of the entire molecule‚ rather than of the individual atoms forming the bonds. 1. The new orbitals are called molecular orbitals. ii. Electrons shared by atoms in a molecule reside in the molecular orbitals. iii. Molecular orbitals are like atomic orbitals

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
