WHAT WILL I LEARN?

Calorimetry means measurement of heat. When a body at higher temperature is brought in contact with another body at lower temperature, the heat lost by the hot body is equal to the heat gained by the colder body, provided no heat is allowed to escape to the surroundings. A device in which heat measurement can be made is called a calorimeter. It consists a metallic vessel and stirrer of the same material like copper or alumiunium. The vessel is kept inside a wooden jacket which contains heat insulating materials like glass wool etc. The outer jacket acts as a heat shield and reduces the heat loss from the inner vessel. There is an opening in the outer jacket through which a mercury thermometer can be inserted into the calorimeter.

We all have common-sense notions of heat and temperature. Temperature is a measure of ‘hotness’ of a body. A kettle with boiling water is hotter than a box containing ice. In this chapter, you will learn what heat is and how it is measured. You will also find out why blacksmiths heat the iron ring before fitting on the rim of a wooden wheel of a bullock cart. You will also learn what happens when water boils or freezes, and its temperature does not change during these processes even though a great deal of heat is flowing
into or out of it.
