Chapter 2, Problem 2B.4ST

Interpretation Introduction

Interpretation:

The heat transferred in the combustion reaction has to be calculated.

Concept Introduction:

For a specified system, the heat capacity $C$ of any substance is given by

$C=\frac{q}{\Delta T}$

Where, $q$ is the heat transferred and $\Delta T=T{f}_{}-T_i$ is the temperature change in the system.

The energy provided electrically to the calorimeter $q_{cal}=IV\Delta t$ ; Where $I$ is the current, $V$ is the voltage and $t$ is the time.
