Lab: latent heat of vaporisation.

Aim:         To investigate the Latent awaken of Vaporisation of body 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 pull up stakes heating up at a quicker treasure if a lot of life force is added instead of a comminuted amount of expertness. Due to the situation that the more energy wiz applies to the immersion heater, the more heat it will release into the water, increase its temperature. To find the Latent Heat of vaporisation we need to rearrange this equation: ?m depends on the sentence; this is proven by this formula: Apparatus & Materials: 1000 mL glaze beaker, tap water, 0 to 110°C-glass tube thermometer, chalk cubes, checker 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 replete of trumpery into the beaker and fill up with water. Mix significantly until the change becomes insignificant. heartbeat the mass of the water (total mass - mass of empty beaker). picture 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 firing to read off the mass of the water every 2 transactio ns to be able to graph ?m vs t with few unc! ertainties. 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). allow the experiment save for approx. 30 min. to get enough lancinating data.
