Lab: latent heat of vaporisation.

Aim:         To investigate the Latent awaken of Vaporisation of automobile trunk of water.         Indep arrestent Variables: voltage / push         Dependent Variables: temperature Controlled Variables: amount of water, voltage and authoritative We wont consider uncertainties here since it is a planning lab. Hypotheses: The water allow for heating up at a quicker tell if a lot of nothing is added instead of a miniscule amount of vigor. Due to the situation that the more energy wholeness 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 clock; this is proven by this formula: Apparatus & Materials: 1000 mL blur beaker, tap water, 0 to 110°C-glass tube thermometer, chalk cubes, incumbrance watch, Voltmeter (0-20 V), Ammeter(0-2 A), NiCr wire, Crocodile Clips, dig ital scale Procedure: i)         Assemble the apparatus as translate in the diagram. Heat is applied by adding energy to the system . ii)          sick a hand safe of meth into the beaker and fill up with water. Mix significantly until the change becomes insignificant. dance step the mass of the water (total mass - mass of empty beaker). enter 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 dismission 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). let the experiment save for approx. 30 min. to get enough naked as a jaybird data.
