<i>1. State the five assumptions of the Kinetic-Molecular Theory of gases.</i><br><br>a) Gases consist of large numbers of tiny particles. These particles‚ usually molecules or atoms‚ typically occupy a volume about 1000 times larger than occupied by the same number of particles in the liquid or solid state. Thus molecules of gases are much further apart than those of liquids or solids.<br><br>Most of the volume occupied by a gas is empty space. This accounts for the lower density of gases compared

Kinetic Molecular Theory Basic Concepts The gas laws developed by Boyle‚ Charles‚ and Gay-Lussac are based upon empirical observations and describe the behavior of a gas in macroscopic terms‚ that is‚ in terms of properties that a person can directly observe and experience. An alternative approach to understanding the behavior of a gas is to begin with the atomic theory‚ which states that all substances are composed of a large number of very small particles (molecules or atoms). In principle‚ the

arena. I had my first glimpse at molecular biology then. But that brief introduction to molecular biology was enough to compel me to the idea that I want to spend my whole life working and conducting research on it. That passion and zeal brought me to where right now I am. I have successfully completed my masters from the Department of Genetic Engineering and Biotechnology‚ University of Dhaka. I want to note that very few universities offer courses related to molecular biology here in Bangladesh but

Investigate a Social Issue – Abuse The social issue that I choose to write about is the abuse. Abuse is defined as the physical injuries to victim perpetrated by other person‚ to treat in an injurious‚ harmful‚ or unpleasant way. There are many diverse kinds of abuse and is vulnerable to anybody at any age and can take place to anyone. The abuse is an issue that exists for a very long time in history. Physical abuse is frequently the most simply recognized appearance. Some

Investigate a Social Issue Eulis Rhodes Tiffani Davis SOC 100 December 9‚ 2013 The social issue that I am interested in is Domestic Violence. Domestic violence is a pattern of abusive and threatening behaviors that may include physical‚ emotional‚ economic and sexual violence as well as intimidation‚ isolation and coercion. The purpose of domestic violence is to establish and exert power and control over another; men most often use it against their intimate partners

Matthew Saldanha Bio DCP lab-Catalase experiment Aim: To investigate enzyme kinetics‚ using different concentration of the enzyme. Hypothesis: The assay system used in the lab consists of a filter paper disc coated with the enzyme and the dropped into a papercup of substrate (Hydrogen Peroxide). As the hydrogen breaks down the hydrogen peroxide into hydrogen and oxygen gas‚ the bubbles of oxygen gas collect underneath the filter and make it

Molecule Polarity PhET Lab A study of electronegativity‚ bond polarity‚ and molecular polarity Introduction: In this atomic-level simulation‚ you will investigate how atoms’ electronegativity value affects the bonds they produce. When two atoms bond‚ a pair of electrons is shared between atoms. Electronegativity is a measure of a single atom’s ability to hoard electrons shared in that bond. In this lab you will work diligently‚ at your own pace‚ to answer a number of questions. To begin‚ from

CENTRAL DOGMA OF MOLECULAR BIOLOGY Molecular Biology Laboratory‚ Biological Sciences Department College of Science and computer Sciences‚ De La Salle University-Dasmarinas ABSTRACT: The central dogma of biology holds that genetic information normally flows from DNA to RNA to protein. In the experiment‚ DNA and RNA bead kits were used. Different coloured beads correspond to different nitrogenous bases‚ sugars and phosphates. Different structures of DNA and RNA were formed based on the sequences
