packed closely together‚ but they are able to move around. Hence a fluid does not have a rigid shape‚ but adapts to the contours of the container that holds it. Like a liquid a gas has no fixed shape‚ but it has little resistance to compression because there is enough empty space for the molecules to move closer. Whereas a liquid placed in a container will form a puddle at the bottom of the container‚ a gas will expand to fill the container. Although the three categories seem very well defined

The History of the Dumas from 1906 to 1914 was a History of lost opportunities by the Tsar and his Ministers’. Assess the validity of this statement. In the setting up of the first duma the tsar and his ministers had the opportunity to meet the demands of the people without having to lose any authority or change the system that was already in place too drastically‚ he also could have given the people representation that they so desperately wanted. The events of Bloody Sunday made the Tsar

Alexandre Dumas‚ père‚ born Dumas Davy de la Pailleterie (24 July 1802 – 5 December 1870)[1] was a French writer‚ best known for his historical novels of high adventure which have made him one of the most widely read French authors in the world. Many of his novels‚ including The Count of Monte Cristo‚ The Three Musketeers‚ Twenty Years After‚ and The Vicomte de Bragelonne were originally serialized. Life [edit] Early life Alexandre Dumas was born in Villers-Cotterêts in the department of

percentage content of ethanol in 3 samples (spirit‚ wine and a beer). We would be comparing the concentration of ethanol to that of 25%propanol which would act as an internal standard. Method To set up the standards for a calibration curve we would make solutions of different concentrations of ethanol. Using a 25cm3 volumetric flask we would put 10cm3 of 25% Propanol into each one which would act as an internal standard. We would then add differing amounts of ethanol (0.5 cm3‚ 1.0cm3‚ 2.0cm3and

Speech I. The history of molecular gastronomy Molecular gastronomy is a new discipline about food science. This science investigates‚ explains and makes practical use of the physical and chemical transformations of ingredients that take place while cooking. But the truth is‚ using this science in cooking is not new. Pioneer Professors Evelyn G. Halliday and Isabel T. Noble: they said in their book “The main purpose of this book is to give an understanding of the chemical principles upon

Different Liquids Objective of the Project This project is of the rate of evaporation of different liquid‚ in which we also discuss the factors which affect the rate of liquid. Introduction When liquid is placed in an open vessel. It slowly escapes into gaseous phase ventually leaving the vessel empty. This phenomenon is known as vaporization or evaporation. Evaporation of liquids can be explained in the terms of kinetic molecular model although there are strong molecular attractive

Molecular modelling is the general term used to describe the use of computers to construct molecules and perform a variety of calculations on these molecules in order to predict their chemical characteristics and behaviour. The term molecular modelling is often used synonymously with the term computational chemistry. Computational chemistry is a broader term‚ referring to any use of computers to study chemical systems. Some chemists use the term computational quantum chemistry to refer to the use

The Man in the Iron Mask‚ by Alexandre Dumas‚ and Hamlet‚ by William Shakespeare‚ both follow similar plot lines and relate to each other through their themes. Shakespeare and Dumas both discuss themes of family‚ justice and judgement‚ lies and deceit‚ loyalty and the consequences of revenge. These major themes blend seamlessly in the stories of Shakespeare’s Hamlet and The Man in the Iron Mask. The themes are consistent throughout the play and the book‚ ultimately addressing the search for truth

Molecular gastronomy Transglutaminase (TG) is a naturally occurring enzyme in plants‚ animals‚ and bacteria. Enzymes are proteins that act as catalysts in chemical reactions; they speed up reactions and make reactions occur that otherwise wouldn’t. Although TG is a newcomer to the kitchen‚ cooks have used enzymes for thousands of years. Enzymes in papaya‚ for instance‚ are traditionally used as meat tenderizers. The enzyme rennet is used to curdle milk when making cheese. Enzymes that break down
