Heat conduction is the transfer of thermal energy within a material or between materials in direct contact, occurring due to the temperature gradient. This process is governed by Fourier's Law, which states that the heat transfer rate is proportional to the negative gradient of temperature and the material's thermal conductivity.

Heat Conduction

Heat conduction

Thermal energy is the internal energy present in a system due to the random motions of its particles, often associated with temperature and heat transfer. It plays a crucial role in thermodynamics, influencing how energy is transferred and transformed in physical processes.

thermal energy

A temperature gradient is the rate of temperature change in a particular direction, often measured per unit distance. It is a critical factor in various natural and engineered processes, influencing heat transfer, weather patterns, and ocean currents.

temperature gradient

Fourier's law, also known as the law of heat conduction, states that the rate of heat transfer through a material is proportional to the negative gradient of temperature and the area through which the heat flows. This fundamental principle is crucial in understanding and designing thermal systems, as it describes how heat energy is conducted through materials in response to temperature differences.

Fourier's Law

The heat transfer rate is the amount of heat energy transferred per unit time from one system to another due to a temperature difference. It is a fundamental parameter in thermal engineering, influencing the efficiency and effectiveness of heating and cooling systems.
