Chapter 17, Problem 57A

Interpretation Introduction

Interpretation: The device used to measure the heat released during constant volume is to be named and discussed.

Concept Introduction:

Calorimetry is used to measure the amount of heat involved in a chemical or physical reaction. The heat change during a chemical reaction leads to a change in temperature, which is used to measure enthalpy.

Answer to Problem 57A

The device used to measure the heat released during constant volume is Bomb Calorimeter.

Explanation of Solution

Heat is transmitted from the calorimeter to the system and the calorimeter's temperature drops if the reaction absorbs heat. Similarly, if the reaction produces heat, heat is passed from the system to the calorimeter, raising its temperature.
