Out of the three metals A, B and C of specific heat 900 J kg-1 °C-1, 380 J kg-1 °C-1 and 460 J kg-1 °C-1 respectively, which will you prefer for calorimeter? Given reason.
Answers
Answer:
The metal B of specific heat capacity 380 J kg-1 °c-1 should be used because it will take the least amount of heat from the contents to attain the temperature of the contents.Read more on Sarthaks.com - https://www.sarthaks.com/261400/you-have-a-choice-of-three-metals-a-b-and-c-of-specific-heat-capacities-900-jkg-1
Answer:
Heat energy required to raise the temperature of the body is given by Q=mSΔT
where S is the specific heat capacity of the body.
So, more is the specific heat of the body, more is the heat energy required to rise its temperature by 1
o
C and vice-versa.
Hence the material of the calorimeter should
have least specific heat capacity so that less heat energy is required to rise its temperature. So, we must select the metal B to make calorimeter.
