Answer:

conduction phenomenon

Explanation:

The heat is transported from one end to the other end by the conduction phenomenon. The molecules of the metallic rod get energy from the heating medium and collide with the neighbouring molecules

Heat can be transferred from one place to another by mainly 3 processes:

  • Conduction

  • Convection

  • Radiation

Both conduction and convection involves movement of medium particles to transfer the heat. However radiation can transfer heat without any medium.

Heat transfer requires a temperature gradient, such that heat current travels from higher temperature to lower temperature.

For example;

Expression for heat current in conduction through a material of thermal conductance (k) , area (a) and length (l):

 \boxed{ \sf{H =  \dfrac{( \theta1  -  \theta1)}{ (\frac{l}{ka} )} } =  \frac{temperature \: diff.}{resistance} }
