Textbook Problem

The freezing point of mercury is ―38.8 °C. What quantity of energy, in joules, is released to the surroundings if 1.00 mL of mercury is cooled from 23.0 °C to ―38.8 °C and then frozen to a solid? (The density of liquid mercury is 13.6 g/cm3. Its specific heat capacity is 0.140 J/g · K and its heat of fusion is 11.4 J/g.)

Interpretation Introduction

Interpretation:

The energy released when mercury is cooled at different temperatures to its freezing point has to be calculated.

Concept Introduction:

Heat energy required to raise the temperature of 1g of substance by 1k.Energy gained or lost can be calculated using the below equation.

  q=C×m×ΔT

Where,

  q= energy gained or lost for a given mass of substance (m),

  C =specific heat capacity

  ΔT= change in temperature

Explanation

Given,

  Freezing point of mercury=-38.80C

  Volume =1mL

  Density of mercury =13.6g/cm3

  Specific heat capacity=0.140JK/g

  Heat of fusion=11.4J/g

Mass =Density × volume

Substitute for the equation,

  Mass=13.6g/cm3×1mL=13.6g

q1= Decrease the temperature from 23.00C to 00C

           q=C×m×ΔT

Substitute for the equation as

  q1=0
