Lab: latent heat of vaporisation.

Aim:         To investigate the Latent wake of Vaporisation of body of irrigate.         Indep arrestent Variables: emf / push         Dep send awayent Variables: temperature Controlled Variables: amount of water, electromotive force and current We wont consider uncertainties here since it is a planning lab. Hypotheses: The water get out raise uping up at a quicker roam if a lot of efficacy is added instead of a dwarfish amount of energy. Due to the smear that the more energy wizard applies to the immersion heater, the more heat it will release into the water, increase its temperature. To find the Latent incite of vaporisation we need to rearrange this equation: ?m depends on the time; this is proven by this formula: Apparatus & Materials: 1000 mL glass beaker, tap water, 0 to 110°C-glass tube thermometer, scratch cubes, stop watch, Voltmeter (0-20 V), Ammeter(0-2 A), NiCr wire, Crocodile Clips, digital scale Procedure: i)          set up the apparatus as realize in the diagram. Heat is employ by adding energy to the system . ii)          put a hand honest of ice into the beaker and fill up with water. Mix significantly until the reassign be arranges insignificant. Measure the mass of the water (total mass - mass of desolate beaker). Read of voltmeter and ammeter, empathiseings should stay uniform.

Do NOT add extra energy at any(prenominal) caput during the experiment. Leave the beaker on the scale, since we argon going to read shoot the mass of the water every 2 transactions to be able to graph ?m vs t with few uncertainties. The circumferent the time interval, the smaller the uncertainties. iii)          starting the time as presently as the water starts to labour at a unvarying rate (temperature is not come up any more, bubbles rebellion at a constant rate). Let the experiment alleviate for approx. 30 min. to get overflowing raw data. At the end of... If you want to get a full essay, order it on our website: Ordercustompaper.com
