To find the specific heat of a given solid
Materials required -calorimeter,thermometer, stirrer, water,steam heater,wooden box and lead shots.
Procedure :-
1.measure the mass of calorimeter with stirrer=m1gm.
2.fill water one third volume of calorimeter and measure the mass =m2gm.
3.at this time initial temperature =T1
4.mass of the water =m2-m1gm
5. Take a few lead shots in steam heater and heat upto 100degree Celsius let this temperature Be T2
6.pour the lead shots into calorimeter and measure the final temperature T3
Mass of calorimeter with contents =m3gm and mass of lead shots =m3-m2gm
If specific heats of the calorimeter, lead shots, and water are Sc,Sl, Sw respectively
By using method of mixtures we have
Heat lost by the solid =heat gain by the (calorimeter +water)
(m3-m1)Sl(T2-T2)=M1sc(T3-T1)+(m2-m1)Sw(T2-T3)
Sl=[M1SC+(M2-M1) Sw](T3-T1) /(m3-m2)(T2-T3)
Knowing the specific heats of calorimeter nd water we can able to calculate specific heat of solid.

Plzz mark best...
have u copied this from anywhere?
I hav learnt it in my school.
do u have fb
Ya
Plzz mark it best......
1st give ur fb id
Okk
But I cannot give it in comments I will send you in msgs
try to format your answer into paragraphs. that will be more readable.
