Chapter U5.101, Problem 4E

Interpretation Introduction

Interpretation: The term calorimetry needs to be defined.

Concept introduction: Combustion is a chemical reaction where a compound or an element undergoes reaction with oxygen and releases energy in the form of light and heat. Combustion of covalent compounds comprising carbon and hydrogen produces carbon dioxide and water. The combustion of metallic substance produces metal oxide.

Answer to Problem 4E

The process of measurement of heat energy released or absorbed in a chemical reaction is known as calorimetry.

Explanation of Solution

Calorie is a unit of energy. Food calorie means the amount of energy we get from our food. To measure food calorie, the amount of energy released when food reacts with oxygen, that is, combustion reaction needs to be calculated. The science of measuring released or absorbed energy in a chemical reaction or physical change is termed as calorimetry.

Conclusion

Calorimetry is a process to measure heat energy of a reaction.
