| Chemistry Lab Report | Constructing Heating/Cooling Curve | | Salman Ishaq 12-E | 1/27/2013 | | BACKGROUND As energy flows from a liquid‚ its temperature drops. The entropy‚ or random ordering of its particles‚ also decreases until a specific ordering of the particles results in a phase change to a solid. If energy is being released or absorbed by a substance remaining at the same temperature‚ this is evidence that a dramatic change in entropy‚ such as a phase change‚ is occurring. Because

THE COOLING PUMPS AND COOLING SYSTEMS DEFINITION OF TERMS Cooling System - equipment in a motor vehicle that cools the engine. Water Cooling is a method of heat removal from components and industrial equipment. As opposed to air cooling‚ water is used as the heat conductor. Water cooling is commonly used for cooling automobile internal combustion engines and large industrial facilities such as steam electric power plants‚ hydroelectric generators‚ petroleum refineries and chemical plants

Background Research Gelatine is a clear‚ colorless‚ brittle (when dry)‚ flavourless solid substance‚ derived from the collagen inside the skin and bones of animals. Substances containing gelatine or functioning in a similar way are called gelatinous. gelatine is an irreversibly hydrolysed form of collagen. It is found in some gummy candies as well as other products such as marshmallows‚ gelatine dessert‚ and some low-fat yogurt. Household gelatine comes in the form of sheets‚ granules‚ or powder

NS 10.5 (pg 1 of 2) Heating and Cooling Curves What happens when we heat a sample of ice that is initially at -15°C? The addition of heat causes the temperature of the ice to increase. As long as the temperature is below 0°C‚ the sample remains frozen. When the temperature reaches 0°C (the melting point of water)‚ the ice begins to melt. Because melting is an endothermic process‚ the heat we add at 0°C is used to convert ice to water and the temperature remains constant until all the ice

Consumer Problem-solving activity: New car purchase Problem Recognition Problem recognition is comparing a person’s ideal situation against actual. Recently‚ my family has been considering whether our current car is meeting the needs of our family of 5. The kids are getting older and are involved in sports and music that require more transportation space for sports gear‚ musical instruments and the need for more “elbow” space. We would like to go on road trips for family vacations and visit
