उत्तर
A calorimeter is a device used to measure the quantity of heat transferred to or from an object.
It is made of copper because:
i. Copper is a good conductor of heat so it attains the temperature of its contents in a very short time.
ii. It has low specific heat (390 Jkg-1K-1). Therefore, it will take only a very little part of the heat energy given out in the experiment.
