# Heat transfer- Conduction

Heat transfer is a process or can say a discipline of thermal engineering that goes hand in hand with the generation, use, and exchange of thermal energy or heat between the physical systems. Heat conduction has given many terms scientifically but mainly it is called diffusion and it is the direct microscopic exchange of kinetic energy of particles through the boundary between two systems so when an object is at a differentiated by temperature from another body or surroundings or near bodies, heat flows so that the surrounding and body reaches the same temperature at which point they are thermal equilibrium. Let us take an example of a steady-state of conduction is basically heat flow through walls of a warm house on a cold night this means the temperature within the room is steady as compared to the temperature outside the room.

## Conduction and its mechanism

Conductions are also known as diffusion which are those who transfer of energy between objects that are in physical contact. There is a property in which material conduct heat which is known as thermal conductivity. Mechanism of the consumption is on a microscopic scale where heat conduction occurs as hot, rapid-moving or vibrating atoms and molecules interact with neighboring atoms and molecules which help to transfer some of their heat to their neighboring particles. Conduction is the most significant and most important means of heat transfer within a solid or solid object in thermal contact. In other words, the process of heat transfer from one place to another place without the movement of particles is widely known as conduction.

## What is a transient conduction?

Conduction has a part known as transient conduction and it occurs when the temperature within an object changes as a function of time and its analysis is more complex and solutions mainly analytical solutions are only valid for the idealized model system. It also includes the heat equation in which an important partial differential equation that describes the distribution of heat or also known as variations in the temperature in a given reign over time. Also, it included lump system analysis as it often reduces the complexity of the equations to one first-order linear differential equation. In this particular method, the ratio of the conductive heat resistance within the object to the convective heat transfer resistance across the object’s boundary is simply known as biot number and it is calculated and the radiant heat transfer is studied by climate models by using quantitative methods to stimulates the interaction of the atmosphere and so on.
