Applied Physics Lecture: Heat

Lesson Objectives – the students should be able to:

  • Convert from joules to calories and kilocalories and vice versa.
  • Distinguish between the concepts of temperature and heat.
  • Explain what is meant by specific heat, latent heat of fusion, and latent heat of vaporization.
  • Apply the law of conservation of energy to problems involving calorimetry.
  • Distinguish the three ways that heat transfer occurs: conduction, convection, and radiation.
  • Solve problems involving the rate of heat transfer by convection and radiation.

Summary of Chapter 14

  • Internal energy U refers to the total energy of all molecules in an object. For an ideal monatomic gas,
    Ideal gas law Formula
  • Heat is the transfer of energy from one object to another due to a temperature difference. Heat can be measured in joules or in calories.
  • Specific heat of a substance is the energy required to change the temperature of a fixed amount of matter by 1° C.
  • In an isolated system, heat gained by one part of the system must be lost by another.
  • Calorimetry measures heat exchange quantitatively.
  • Phase changes require energy even though the temperature does not change.
  • Heat of fusion: amount of energy required to melt 1 kg of material.
  • Heat of vaporization: amount of energy required to change 1 kg of material from liquid to vapor.
  • Heat transfer takes place by conduction, convection, and radiation.
  • In conduction, energy is transferred through the collisions of molecules in the substance.
  • In convection, bulk quantities of the substance flow to areas of different temperature.
  • Radiation is the transfer of energy by electromagnetic waves.
