Answer:
Calorimeter is a device used to measure heat and consists of two vessels. The outer and the
inner steel vessel has a space packed with wool. This allows minimum loss of heat between the
two vessels. A thermometer and a stirrer is inserted into the calorimeter through an orifice in
the tid. The lid is sealed. Water is poured into the inner vessel and the temperature is noted
down with the help of the thermometer. A hot object, either a heated iron nail or a heated
iron ball is put into the water. The temperature of the water is noted. The difference in the
temperature tells the temperature of the hot object

Answer:
The air between the two vessels acts as a heat insulator, meaning there is no (or minimal) heat exchange between what is inside the inner vessel and the outside environment.
