FIRE TRIANGLE In order to understand how fire extinguishers work‚ you first need to know a little bit about fire. Four things that must be present at the same time in order to produce a fire : * Enough oxygen to sustain combustion. * Enough heat to raise the material to its ignition temperature. * Some sort of fuel or combustible material. * The chemical‚ exothermic reaction that is fire. Take a look at the following diagram called the “Fire Triangle”. Oxygen‚ heat‚ and fuel

Q. Describe the Basic operations of a typical Air Cycle Systems. Basic Operations of a Typical Air Cycle Systems Air cycle machines are not a new technology. At the beginning of the 19th century Air cycle systems used for providing chilling on ships and for food producers and retailers to provide cooling for their food stores. So those days these kinds of air cycle machines were available from companies such as J&E Hall. From the development of the aircrafts people start building pressurised aircraft

PHYS 124 – 3:30 Th Lab 5: Joule Heat John Doe 4/3/2014 Introduction The objective of this lab is to learn that whenever there is an electrical current in a conductor‚ there is some electrical energy that is converted into heat energy. The heat generated in an electrical circuit is commonly referred to as joule heat. Sir James Joule studies of these separate phenomena lead him to the discovery of the proportionality constant known as the Joule equivalent of heat‚ denoted by J. The Joule equivalent

Research Question Investigate the effect of temperature on the rate of respiration of various parts of plants (germinating seeds and dormant (non-germinating) seeds)‚ by measuring the oxygen consumption and change in gas volume of respirometers containing either germinating or non-germinating seeds at different temperatures to measure the rate of respiration of these beans at different temperatures. Hypothesis 1.Germinating seeds have a higher rate of respiration as compared to non-germinating

The human body is made up of trillions of cells that all work together for the maintenance of the entire organism. While cells‚ tissues‚ and organs may perform very different functions‚ all the cells in the body are similar in their metabolic needs. Maintaining a constant internal environment by providing the cells with what they need to survive (oxygen‚ nutrients‚ and removal of waste) is necessary for the well-being of individual cells and of the entire body. The many processes by which the body
