Differentiate clearly between thermal conduction,thermal convection,and thermal radiation.

(N/A) Thermal energy can be transferred through three distinct mechanisms:
$1$. Thermal Conduction: Heat transfer in solids where particles vibrate about their mean positions without net displacement. It does not require gravity and does not involve the formation of currents.
$2$. Thermal Convection: Heat transfer in fluids (liquids and gases) where particles physically move from one region to another,carrying thermal energy. This process requires gravity and leads to the formation of convection currents.
$3$. Thermal Radiation: Heat transfer in the form of electromagnetic waves (specifically infrared radiation). It does not require any material medium for propagation and can occur in a vacuum.
