Question Question 9(a)
(i) Define Calorimetry. [3]
(ii) Name the material used for making a Calorimeter.
(iii) Why is a Calorimeter made-up of thin sheets of the above material answered in (ii) ?
(i) The science of measuring the amount of heat exchanged by the system with it's surrounding is called calorimetry.
(ii) A copper sheet is used to make a calorimeter.
(iii) It is because Copper is a good conductor of heat so it soon acquires the temperature of it's contents and a thin Copper sheet has low heat capacity, so it takes only a small amount of heat from it's contents. Hence, a Calorimeter is made-up of thin sheets of Copper.
