Question

How can the heat capacity of a lead sinker be determined?

Answer 1

Heat capacity or thermal capacity is a physical property of matter, in which heat is supplied on a unit mass to observe a unit change in its temperature.

Complete step by step answer:
Lead sinker: It is a weight attached to the fishing rod, to increase the rate of sink of the rod.
Heat capacity: It is a physical property of matter, defined as the amount of heat to be supplied to a given mass of a material to produce a unit change in its temperature. The SI unit of heat capacity is joules per Kelvin.

Calorimeter: A calorimeter is an object used for Calorimetric measurements, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity.
In order to find the heat capacity of the lead sinker, a calorimeter is used.
Let us suppose we have a lead sinker of 5g, which is placed in 200ml of distilled water in the calorimeter, which is heated up and then we will record the temperature using the thermometer.

Note: Materials which have small specific heat capacity are very useful as a cooking instrument material such as frying pan, pots, kettles and so on, because they can be heated up even when a small amount of heat is applied to the utensils. Sensitive thermometers also must be made from materials with small specific heat capacity so that temperature variation can be easily detected.
