determine the specific heat of solid by using method of mixtures
Answers
To determine the specific heat of given liquid by method of mixture, instead of cold water, take the liquid whose specific heat is to be determined and proceeded as in the experiment done for determining the specific heat of solid. The specific heat of solid is already calculated.
Aim
To determine specific heat capacity of a given solid by method of mixtures.
Procedure
Put two thermometer A and B in a beaker containing water and note their reading. Take one of them, say A to be standard and find the correction to be applied to the other, say B.
Put thermometer B in copper tube of hypsometer containing the power of given solid. Put sufficient water in hypsometer and place it on a burner.
Weigh the calorimeter with stirrer and lid over it by the physical balance. Record it.
Fill about half of calorimeter with water at about temperature 5 to 8°C below room temperature. Now, weigh it again and record it.
Heat the hypsometer about 10 minutes till the temperature of solid remains steady.
Note the temperature of water in the calorimeter. Now, transfer the solid from hypsometer to the calorimeter quickly. Stir the contents and record the final temperature of the mixture.
Remove the thermometer A from calorimeter and weigh the calorimeter with its contents and lid.
