Question

Why is a calorimeter box made up of copper?

Answer 1

Hint: A calorimeter is an object applied for calorimetry or estimating the heat of chemical effects or physical changes and heat capacity. Calorimeter is formed of copper because Copper is a good heat conductor, copper has low specific heat capacity, negligible heat is received/delivered to by light copper wall.

Complete answer:
A calorimeter is a device utilized to estimate the quantity of heat transported to or from an object. Cu is highly flexible, and a hence skinny box of small mass can be formed. Copper is a good heat conductor. Calorimetry is the method of estimating the amount of heat released or absorbed during a chemical reaction. A calorimeter is made of copper because Copper has a minute-specific heat capacity, and the lightbox assures that the box has a small heat capacity. Thus the calorimeter box can receive a small amount of heat from the calorimeter's contents.
A calorimeter box is formed up of copper because
a) Cu has moderate specific heat capacity, and thus it leads the equilibrium temperature immediately by absorbing a small quantity of heat. This small quantity of heat absorption does not influence the natural rate of the chemical effect occurring in the calorimeter.
b) Cu is very malleable, and hence a fragile box of small mass can be formed, thus reducing the heat capacity of the box. This executes sure the calorimeter receives or releases a small quantity of heat during the heat transfer.
c) Cu is a good conductor of heat, which means it can raise its temperature to measure heat flow by absorbing a small amount of heat.

Note: A calorimeter is stored in a wooden box so that no heat disappears from it due to convection. If the calorimeter is not placed in a wooden box, heat will depart from it to the surroundings when elements are mixed, and the correct amount of heat energy will not be estimated.
