SLOs Of 9th Class Physics Notes Transfer Of Heat

By studying Transfer Of Heat 9th Class physics notes students will be able to:
The material presented here is to help students and for only the educational purpose. 
  • Recall that thermal energy is transferred from a region of higher temperature to a region of lower temperature. Describe in terms of molecules and electrons how heat transfer occurs in solids. 
  • State the factors affecting the transfer of heat through solid conductors and hence, define the term Thermal Conductivity. Solve problems based on thermal conductivity of solid conductors. 
  • Write examples of good and bad conductors of heat and describe their uses. 
  • Explain the convection currents in fluids due to difference in density. 
  • State some examples of heat transfer by convection in everyday life. 
  • Explain insulation reduces energy transfer by conduction. Describe the process of radiation from all objects. 
  • Explain that energy transfer of a body by radiation does not require a material medium and rate of energy transfer is affected by:

  1. Colour and texture of the surface
  2. Surface temperature
  3. Surface area
