Answer to Problem C18.5RE

Total heat that transferred to the pot is 131250 cal.

Explanation of Solution

Given 5 kg iron pot is filled with 500 Ml of water.

The energy for water is as follows:

Mass of water

  (m)=500mL=500mL×gmL=500g

  (density=1g/mL)

Temperature change

  (ΔT)=150°C25°C=125°C

Specific heat of water is 1cal/g°C

The equation of heat is as follows:

  H1=mCΔT

Here H is heat, m is mass, C is specific heat and T is temperature.

Put the values in above equation is as follows:

  H1=500g×1cal°C×125°C=62500cal

The energy for iron is as follows:

Mass of water

  (m)=5kg=5000g

Temperature change

  (ΔT)=150°C25°C=125°C

Specific heat of iron is 0.11cal/g°C

The equation of heat is as follows:

  H2=mCΔT

Here H is heat, m is mass, C is specific heat and T is temperature.

Put the values in above equation is as follows:

  H2=5000g×0.11cal°C×125°C=68750cal

Thus,

  total energy is=H1+H2=62500cal+68750cal=131250cal

Therefore total heat that transferred to the pot is 131250 cal.

Interpretation Introduction

Interpretation: The number of calories of energy transferred by rise the temperature of 200g of copper by 50°C needs to be calculated.

Concept Introduction: Thermodynamics is the analysis of heat transfer. Heat transfer direction is always from a hotter substance to colder one.

Answer to Problem C18.5RE

Iron pot will cool faster than water pot. This is because iron has less specific heat capacity than water.

Explanation of Solution

After heating same temperature for three minutes iron pot will cool faster than water pot. This is because iron has less specific heat capacity than water.
