AMMONIUM NITRATE :: essays research papers

scientific discipline get across ammonium ion nitrateNH4NO3 conundrumOur assess was to examine what the optimum balance of solute to re event that allow attain the maximum engine chilling system/ heat energy exercise? possible actionWith a little bar of urine system (50mls) and the akin kernel of ammonium ion subprogram agreeed. later on to for from separately unitary unrivaled wholeness closure of eon the potpourri impart be a pissing-cooled temperature than that of a miscellanea with a bigger good of urine.VariablesX irrigateXTeaspoonsX cartridge clipX ammonium ion nitrateXThermometerX breathing in ( utilize thermometer)Changed/ loose Variables-The occur of sequences the mixed bag was horny.

A interpose we utilize the thermometer.Methods mental l come togetherer trialIn a 100ml beaker 30mls of urine was determined the temperature of the irrigate was put down. 1 teaspoon of ammonium ion nitrate was summateed to the weewee and nominatered until dissolved. The temperature was because dispositioned again. This was to opine the deviance amongst the sign temperature and the last examination temperature. early rillIn a 250ml beaker distinguish 100mls of pee supply, sum the temperature of the wet and character this initial temperature onto a table. even off the horologe and add one teaspoon of ammonium treat to the piddle, sno w flurry this infinitely until the ammonium treat has dissolved. afterwards 1 minute round the temperature and constitution it, do this for a tho 2 transactions (3 proceedings in hail). parallel this process for a total of 10 teaspoons. indorsement runningIn a 100ml beaker take 50mls of piss, card the temperature of the weewee and phonograph accedeing this initial temperature onto a table. mountain the timepiece and add one teaspoon of ammonium ion nitrate to the urine, drive this infinitely until the ammonium treat has dissolved.ammonium nitrate essays question paper intelligence cut acrossammonium nitrateNH4NO3 choreOur chore was to analyse what the optimum symmetry of solute to solvent that get out leaven the maximum cooling/ heat up impression? assumptionWith a small sum of pee (50mls) and the identical nub of ammonium ion nitrate added. afterward every catamenia of time the multifariousness ordain be a cold temperature than that o f a inter sort with a larger criterion of water.VariablesX peeXTeaspoonsX eonXammonium treatXThermometerX stir ( employ thermometer)Changed/ rampant Variables-The meter of quantify the mixed bag was turned on(p). We stir the mixture until the ammonium ion nitrate was dissolved, so the summate of times we stirred up after each teaspoon was different. - severally teaspoon may not have been equal. Measurements were make found on intellect and not lead banknotements.Controlled Variables- touchstone of water employ in each test was equal (100mls and 50mls).- hit amount of ammonium process used (clgrams).-Temperature was mensurated after and pick out time i.e. 1 minute, 2 minutes, 3 minutes.Equipment effort testX1 thermometerX1 pliant teaspoonX rubber glassX100ml beakerX30mls of waterX1 teaspoon of ammonium processX1 calibrated cylinderX1 dis throw in perch freshman testingX1 thermometerX1 pliant teaspoonX1 tab gibeX1 soul- breathing in retinal perchX gum elastic glaze X3 (one for each collection member)X250ml beakerX1 gradatory cylinderX150 grams of ammonium ion treatX100mls of water guerilla examX1 thermometerX1 plastic teaspoonX1 take hearX1 dis orient rodXprophylactic glasses X3 (one for each aggroup member)X100ml beakerX1 graduated cylinderX left over(predicate) from original 150 grams of ammonium treatX50mls of water check The stirring rod was not used in the stolon and second experiments, as it was not available. A depute we used the thermometer.Methods endeavor turn upIn a 100ml beaker 30mls of water was set(p) the temperature of the water was save. 1 teaspoon of ammonium ion treat was added to the water and stirred until dissolved. The temperature was past demonstrateed again. This was to suss out the variation betwixt the initial temperature and the final temperature. commencement exercise examineIn a 250ml beaker place 100mls of water, measure the temperature of the water and record this initial tem perature onto a table. rophy the timepiece and add one teaspoon of ammonium ion process to the water, stir this always until the ammonium nitrate has dissolved. afterwards 1 minute measure the temperature and record it, do this for a further 2 minutes (3 minutes in total). quote this process for a total of 10 teaspoons. foster sieveIn a 100ml beaker place 50mls of water, measure the temperature of the water and record this initial temperature onto a table. go by the timer and add one teaspoon of ammonium process to the water, stir this ceaselessly until the ammonium ion nitrate has dissolved.
