Latent Heat Of Vaporization

AIM: To find the latent horniness of vaporization of water system system. MATERIALS required: * Copper Calorimeter * Thermometer * pee trap * Cotton woollen * Bunsen burner; Metal netting; Conical flask; Tripod balk * Dry steamer trap (Bent tube) * Water trap * sift METHOD: The specific latent soup up of vaporization of water can be found by lane steam into water in a calorimeter, where it condenses and releases its latent vex. The appliance is as shown in the figure above. 1. Weigh the calorimeter empty. 2. Reweigh the calorimeter when it is about half replete of water. 3. The temperature of the water is read and recorded. 4. Set up the instrument as shown in the diagram 5. The calorimeter is lagged with cotton wool to insulate it from the rouse of the surroundings. 6. Turn on the Bunsen burner and allow the water to boil. buy the farm from the boiler is passed through a steam trap to tag aside any condensed moisture. Dry steam only therefore, is allowed to pass into the water in the calorimeter. 7. A screen is usually laid in the midst of the boiler and the calorimeter to prevent the latter from receiving heat directly from the boiler. 8.

The pass of dry steam into the calorimeter is stopped when the temperature of the calorimeter rises by about 30?C above room temperature. 9. Finally, reweigh the calorimeter and content to find the set of steam condensed.
