    Thermal Conduction is the transfer of internal energy by microscopic collisions of particles and movement of electrons within a body. The colliding particles, which include molecules, atoms and electrons, transfer disorganized microscopic kinetic and potential energy, jointly known as internal energy. Conduction takes place in all phases: solid, liquid, and gas. The rate at which energy is conducted as the heat between two bodies depends on the temperature difference (and hence temperature gradient) between the two bodie

Thermal conductivity is the property of a material to conduct heat and evaluated primarily in terms of Fourier's Law for heat conduction. Convection The transfer of energy between an object and its environment, due to fluid motion. The average temperature is a reference for evaluating properties related to convective heat transfer. Radiation The transfer of energy by the emission of electromagnetic radiation.By transferring matter, energy—including thermal energy—is moved by the physical transfer of a hot or cold object from one place to another. This can be as simple as placing hot water in a bottle and heating a bed, or the movement of an iceberg in changing ocean currents. A practical example is thermal hydraulics. This can be described by the formula: $${\displaystyle \phi _{q}=v\rho c_{p}\Delta T}$$where • $${\displaystyle \phi _{q}}$$ is heat flux (W/m ),• $${\displaystyle \rho }$$ is density (kg/m³),• $${\displaystyle c_{p}}$$ is heat capacity at constant pressure (J/kgK),• $${\displaystyle \Delta T}$$ is the difference in temperature (K),
