Gas exchange is the movement of respiratory gases across a membrane. It is the delivery of oxygen to the body‚ and the elimination of carbon dioxide from the body .The reason why gas exchange takes place because oxygen is one of the most essential requirements of life‚ without which organisms on Earth would not survive. Living organisms generate energy from food through the process of respiration. This allows humans and other organisms to perform their daily tasks. Oxygen is used in mitochondria

York 3 Vroom! Diesel mechanics proves to be an interesting career. There are many tools needed in this area to fulfill the career‚ which means money. Diesel engines have been around for a long time now. This job field covers several different kinds of jobs such as truck mechanics and repair and maintenance. A Diesel engine is an engine that starts itself by compression. These engines first started in America. The first diesel engine was invented in 1892. In 1930 they started putting the

Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to
Premium Gas chromatography Chromatography Gas
Gas chromatography (GC) is a chromatography technique where the separation of individual components (analytes) from a sample relies on their differing distribution between a mobile and stationary phase. The mobile phase carries the analytes through the stationary phase. In GC‚ it’s an inert gas (usually helium or nitrogen). The gas must be inert‚ so it won’t react with the sample to give a false reading. The stationary phase is a substance fixed in place to which the sample adsorbs because

Data and Conclusions: The purpose of this experiment was to learn how to use distillation and gas chromatography to separate and identify different compounds from a given mixture. There are several kinds of distillation methods. However‚ the method that we used in this experiment was fractional distillation. This method is used when trying to separate two different volatile compounds whose boiling points differ by 40-50°C or more. If the boiling points are too close‚ this method

Gas analysis techniques Terms for gas analysis techniques Concentration The term concentration describes the amount of a substance‚ expressed as mass‚ volume‚ or number of particles in a unit volume of a solid‚ liquid‚ or gaseous substance e.g. alcohol in beer or oxygen in air. Different units are in use to describe concentration in gases: Mass concentration Concentration expressed in terms of mass of substance per unit volume [g substance/m3 gas volume] ¢ Volume concentration Concentration

Review the behavior of the gas phase vs. the liquid phase. Solution: a) The volume of the liquid remains constant‚ but the volume of the gas increases to the volume of the larger container. b) The volume of the container holding the gas sample increases when heated‚ but the volume of the container holding the liquid sample remains essentially constant when heated. c) The volume of the liquid remains essentially constant‚ but the volume of the gas is reduced. The particles in a gas are further apart than
