| 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

Vesicoureteral Reflux‚ Pediatric Vesicoureteral reflux is a condition in which urine from the bladder goes back into the tubes that connect the kidneys to the bladder (ureters). The bladder is a hollow organ in the lower part of the abdomen. It stores urine after the urine is made by the kidneys. In severe cases of vesicoureteral reflux‚ urine may flow back through the ureters and into the kidneys. Vesicoureteral reflux can affect one or both kidneys and ureters. Vesicoureteral reflux can range from

Gastroesophageal reflux disease or GERD. Gastroesophageal reflux disease (GERD) is a more serious form of gastroesophageal reflux‚ which is common. GERD occurs when the Lower Esophageal Sphincter (LES) opens spontaneously‚ for varying periods of time‚ or does not close properly and stomach contents rise up into the esophagus. GERD is also called acid reflux or acid regurgitation‚ because digestive juices called acids rise up with the food. The esophagus is the tube that carries food from

There are a lot of methods of heat transference when cooking. The methods of cooking are classified according to how heat is applied. For example moist methods‚ dry methods ‚ frying and microwave. For example in moist methods of cooking‚ there is boiling‚ poaching ‚ par-boiling . Also steaming that is when the food doesn’t come in contact with the water but is cooked in the steam . The advantage is that there is loss of nutrients ‚easy to digest‚ light texture ‚little attention ‚ and the food

Acid Reflux or Gastroesophageal Reflux Disease (GERD) is caused by stomach acid rise towards the esophagus and cause pain in the solar plexus or a burning sensation in the chest. The cause of acid reflux (GERD) is the proper functioning of the lower esophageal sphincter (LES). LES is a circle of muscle at the bottom of the esophagus. LES serves as the automatic door opens when food or drink down to the stomach. After the food came in‚ the LES will be shut down to prevent the existing food and acid

EXPERIMENT 2: BATCH DISTILLATION AT CONSTANT REFLUX OBJECTIVE: To operate a batch distillation unit at constant reflux. To examine the change in top and bottom composition over time in a batch distillation. PROCEDURES: 1. Perform the general start-up procedures (Section 4). Refer appendix 1. 2. Record initial volume and refractive index of the liquid mixture in the reboiler. 3. Set the heater power to 1.5kW. 4. Set reflux timer to 10 second for set 1 and 30 second for set 2. ( Note: Set 1:

Lesli Brookshire Anatomy and Physics D. Loving Gastroesophageal Reflux Disease Gastroesophageal reflux is a condition in which the contents in the stomach‚ sometimes food‚ sometimes liquid‚ leaks backwards from the stomach into the throat (ncbi). One common cause of Gastroesophageal reflux occurs when there is an abnormality in the stomach called a hiatal hernia. This happens when the top part of the stomach and LES move above the diaphragm‚ a muscle that keeps your chest and stomach separated.
