Explanation:

#What is Calorimetry?

The act or science of measuring the changes in the state variables of a body in order to calculate the heat transfer associated with changes of its states such as physical changes or phase transitions under specific conditions is known as calorimetry. Calorimetry is performed with the help of a calorimeter.

#Calorimeter Principle

Principle of Calorimetry

When two bodies of different temperatures (preferably a solid and a liquid) are placed in physical contact with each other, the heat is transferred from the body with higher temperature to the body with lower temperature until thermal equilibrium is attained between them. The body at higher temperature releases heat while the body at lower temperature absorbs heat. The principle of calorimetry indicates the law of conservation energy, i.e. the total heat lost by the hot body is equal to the total heat gained by the cold body.

Heat Lost = Heat Gained

The heat transfer in a system is calculated using the formula,

q=mcΔt

Where

q is the is the measure of heat transfer

m is the mass of the body

c is the specific heat of the body

Δt is the change in the temperature

Calorimeter Problems

Let us look at the example below to understand how to calculate the heat transfer between two objects.

Answer:- Calorimetry is used to measure amounts of heat transferred to or from a substance. To do so, the heat is exchanged with a calibrated object (calorimeter). ... The temperature change, along with the specific heat and mass of the solution, can then be used to calculate the amount of heat involved in either case.
