Question

What is a calorimeter? Why is it made of copper? Give two reasons.

Answer 1

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.
