SPECIFIC HEAT OF A SOLID - CLASS 10

LAB ACTIVITY: Determination of Specific heat of a solid

Aim: To find the specific heat of given solid

 Material required: calorimeter, thermometer, stirrer, water, steam water, wooden box ,physical balance and lead shots.

Procedure: Step-1: Mass of the calorimeter (m1) =….

Temperature of the calorimeter (T1) =…

Let specific heat of calorimeter = Sc

Step-2: Now fill 1/3rd of the volume of calorimeter with water.

 Mass of the calorimeter + water = m2

Mass of the water= m2 - m1

Temperature of the water (T1) =…..

 Let specific heat of water= Sw

Step-3: Take a few lead shots and place them in hot water or steam water.

Temperature of the lead shots (T2) =...

Let specific heat of lead shots = Sl

Step-4: Transfer the hot lead shots quickly into the calorimeter.

Mass of the calorimeter + water + lead shots = m3

Mass of lead shots = m3-m2

After some time Temperature of calorimeter+ water+ lead shots = T3

According to Principle of method of mixtures

Heat lost by the solid (lead shots) = Heat gain by the calorimeter + Heat gain by the water
