Interpretation Introduction

Interpretation:

Theaffect on the result of the given experiment, when a calorimeter that contained less water than it did when it was calibrated, is to be explained.

Concept introduction:

The bomb calorimeter is a constant volume calorimeter, which is used to measure the heat of combustion.

The relationship between heat change for the calorimeter and heat change for the reaction is

$q_{\text{cal}}=-q_{\text{rxn}}$

The heat change for the reaction in calorimeter is calculated as

$q_{\text{rxn}}=-C_{\text{cal}}\Delta T$

Here, $C_{\text{cal}}$ is the heat capacity of the calorimeter and $\Delta T$ is the temperature change of the substance.
