Question

Name the different modes of transfer of heat.

• A. Conduction, convection, and radiation
  
• B. Conduction, sublimation, and crystallisation
• C. Conduction, calorimetry, and heat transfer
• D. Vapourisation, convection, and evaporation

Answer 1

The correct option is A Conduction, convection, and radiation

Three models of heat transfer are:

Conduction, convection, and radiation

$Conduction$- Transfer of heat from one substance to another by direct contact without mixing of mass.

$Convection$- The transfer of heat through a fluid (liquid or gas) caused by molecular motion.

$Radiation$- Heat is transferred in the form of radiant energy or wave motion from one body to other. No medium is required.
