Lesson-3.1.2- Recognise convection as an important method of thermal transfer in fluids. Relate convection in fluids to density changes and describe experiments to illustrate convection.PreviousLesson-3.1.4- Describe the effect of surface colour (black or white) and texture (dull or shiny) on the emission, absorption and reflection of radiation.Next
