Chapter 10, Problem 10.5VC

Interpretation Introduction

Interpretation:

The change in specific heat capacity of metal has to be identified with correct statement when the warm metal shots are lost during the transfer of the calorimeter.

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,

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

Specific heat capacity:

Specific heat can be defined as quantity of heat required to raise the temperature of $\text{1}\text{g}$ substance by $\text{1°C}$.  The relationship between heat and change in temperature can be expressed by the equation given below.

$\text{q=smΔT}$

Where,

$\text{q=}$ Heat added

s= Specific heat

$\text{m=}$ Mass

$\text{ΔT=}$ Change in temperature.

The unit of specific heat is $\text{J}{\text{g}}^{\text{-1}}\text{.°C}$ .
