Chapter 10, Problem 10.4VC

Interpretation Introduction

Interpretation:

The variation in the results of the experiment has to be given if the reaction was endothermic.

Concept Introduction:

Calorimetry can be defined as the measurement of changes in heat.

Two types of Calorimetry are coffee cup calorimeter and bomb calorimeter.

The change in heat of the system can be determined with the value of the heat capacity of the calorimeter.

The heat capacity of the calorimeter can be given as,

${\text{C}}_{\text{cal}}\text{=}\frac{{\text{q}}_{\text{cal}}}{\text{ΔT}}$

Exothermic and Endothermic reactions:

Heat is flow of thermal energy involving two bodies at various temperatures.  The flow of thermal energy involving two bodies at various temperatures is called as heat.  The flow of heat implies that energy is either released or absorbed on describing about energy changes that takes place during a process.

Exothermic process is the chemical process in which heat is released to the surroundings.

Endothermic process is the chemical process in which heat is absorbed from the surroundings.
