Question 3(iv)

Out of the following metals A, B and C of specific heat capacities 900 J kg⁻¹ °C⁻¹, 380 J kg⁻¹ °C⁻¹ and 460 J kg⁻¹ °C⁻¹ respectively, which one will you prefer for calorimeter? Give reason.

Answer

Metal B should be preferred for calorimeter because it requires a material with low specific heat capacity so the amount of heat energy taken by the calorimeter itself from the contents to acquire its temperature, is very small.
