Question

What are the principles of calorimetry?

Answer 1

$\Large{\textbf{\underline{\underline{According\;to\;the\;Question}}}}$

As when the two bodies of different temperatures are kept in contact then flow of heat between them takes place from the body at the higher temperature to the lower temperature.

This flow continues till both the bodies attain an equivalent temperature.

In this condition :-

Amount of warmth given = Amount of warmth taken

That is,

m1 = Mass of 1st body

m2 = Mass of 2nd body

t1 = Temperature of 1st body

t2 = Temperature of 2nd body

t = Common Temperature

m = Mass of the body

m1s1(t1 - t) = m2s2(t - t2)

Here,

T is the common temperature or the temperature of the mixture.

Answer 2

Explanation:

Calorimetry is the science or act of measuring changes in state variables of a body for the purpose of deriving the heat transfer associated with changes of its state due, for example, to chemical reactions, physical changes, or phase transitions under specified constraints. Calorimetry is performed with a calorimeter.
