Interpretation Introduction

Interpretation:

The variation in the heat absorbed by the water with respect to the heat given off by reaction has to be given if the heat capacity of calorimeter is not small for exothermic reaction.

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.

Heat capacity:

Heat capacity can be defined as quantity of heat required to raise the temperature of the object by $\text{1°C}$.

The other equation that is used to calculate heat from heat capacity can be given by,

$\text{q=CΔT}$

Where,

$\text{C=}$ Heat capacity of calorimeter

$\text{ΔT=}$ Change in temperature

The unit of heat capacity is $\text{J per °C}$
