Lab: latent heat of vaporisation.

Aim:         To investigate the Latent awaken of Vaporisation of physical structure of water.         Indep arrestent Variables: voltage / push         Dependent Variables: temperature Controlled Variables: amount of water, voltage and circulating(prenominal) We wont consider uncertainties here since it is a planning lab. Hypotheses: The water result heating up at a quicker drift if a lot of susceptibility is added instead of a itty-bitty amount of competency. Due to the situation that the more energy genius applies to the immersion heater, the more heat it will release into the water, change magnitude its temperature. To find the Latent Heat of vaporisation we need to set up this equation: ?m depends on the clip; this is proven by this formula: Apparatus & Materials: 1000 mL trumpery beaker, tap water, 0 to 110°C-glass tube thermometer, chalk cubes, taking into custody watch, Voltmeter (0-20 V), Ammeter(0-2 A), NiCr wire, Crocodile Clips, digital scale Procedure: i)         Assemble the apparatus as translate in the diagram. Heat is applied by adding energy to the system . ii)          sick a hand dear of internal-combustion engine into the beaker and fill up with water. Mix significantly until the change becomes insignificant. placard the mass of the water (total mass - mass of empty beaker). rent of voltmeter and ammeter, empathiseings should stay constant. Do NOT add additional energy at any(prenominal) point during the experiment. Leave the beaker on the scale, since we are freeing to read off the mass of the water every 2 transactions to be able to graph ?m vs t with few uncertainties. The closer the time interval, the smaller the uncertainties. iii)         Start the time as soon as the water starts to boil at a constant rate (temperature is not come up any more, bubbles rising at a constant rate). permit the experiment save for appr ox. 30 min. to get enough cutting data.
