Chapter 6.3, Problem 6.4AFP

Interpretation Introduction

Interpretation:

The heat absorbed by $7.65\text{g}$ piece of aluminium foil that is lined at the bottom of an oven when the temperature is raised from $18°\text{C}$ to $375°\text{C}$ is to be calculated.

Concept introduction:

Heat capacity $\left(C\right)$ of a material is the amount of heat needed to raise the temperature of a substance by $1\text{K}$. The formula to calculate heat required is as follows:

$q=\left(C\right)\left(\Delta T\right)$        (1)

Here,

$\Delta T$ is the temperature difference.

$q$ is the heat released or absorbed.

$C$ is the heat capacity of the substance.

Specific heat capacity $\left(c\right)$ of a substance is the amount of heat needed to raise the temperature of $1\text{g}$ of a substance by $1\text{K}$. The formula to calculate heat required is as follows:

$q=\left(\text{mass}\right)\left(c\right)\left(\Delta T\right)$        (2)

Here,

$\Delta T$ is the temperature difference.

$q$ is the heat released or absorbed.

$c$ is the specific heat capacity of the substance.
