Calorimeter is a small container made of a thin sheet of _________ with good thermal conductivity.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. copper.
A calorimeter is a small container made of a thin sheet of copper with good thermal conductivity.
Copper is commonly used for calorimeters because it is a good conductor of heat, has a low specific heat capacity, and can be easily shaped into a thin sheet, allowing it to quickly reach thermal equilibrium with the substances inside it.
