To determine the specific heat capacity of a given metallic solid using the method of…show more content…
If a substance releases heat, then Q is negative. Heat lost is equal to heat gained. APPARATUS/MATERIAL REQUIRED (i) Copper calorimeter (ii) Thermometer (iii) Water bath (iv) Beaker of water (v) Metal piece (vi) Thread. Diagram from Elementary Practical Physics by Draycott and Lyon PROCEDURE 1. Put some water in a beaker and heat it on the tripod over the gauze. 2. When the water is being heated, find the mass m1 of the solid. 3. Tie the thread to the solid. Now put the solid in the beaker of water which is being heated. See that the free end of the thread attached to the solid is out of the beaker. Leave the water on the tripod and the gauze until it comes to a boil. 4. In the mean - time weigh the dry calorimeter and stirrer. Call this m2. 5. Now take some tap water in the calorimeter. The amount or water taken should be enough to immerse the solid. Find the mass m3, of the calorimeter, stirrer and the water together. 6. Take and record the temperature of the water in the calorimeter. Call it t1C. 7. The calorimeter is placed in a bigger vessel which is well lagged to reduce loss of heat. 8. When the water in the beaker begins to boil, let it do so for about five minutes, so that the solid in it attains a uniform temperature and then record the temperature of boiling water, t2C which is also the temperature of the solid. 9. Remove the solid from
