Questions and Answers

What is the process by which heat is transferred from the hotter end to the colder end of an object?

  • Conduction (correct)
  • Thermal equilibrium
  • Convection
  • Radiation
  • In conduction, where does the heat flow occur?

  • Within and through the body itself (correct)
  • Only on the surface of the body
  • In the absence of a temperature gradient
  • Between separate bodies

  • Heat resistance
  • Thermal diffusivity
  • Temperature gradient
  • Thermal conductivity (correct)
