lämpöenergiaaksi

Lämpöenergiaaksi, also known as thermal energy or heat energy, is the internal energy of a thermodynamic system associated with the kinetic energy of its constituent atoms and molecules. These particles are in constant random motion, and their collective motion contributes to the overall thermal energy of the substance. The greater the motion of these particles, the higher the thermal energy. Temperature is a measure of the average kinetic energy of these particles.

Thermal energy is a form of energy that can be transferred between systems or objects through processes like conduction, convection, and radiation. Conduction involves the transfer of heat through direct contact between particles. Convection is the transfer of heat through the movement of fluids (liquids or gases). Radiation is the transfer of heat through electromagnetic waves.

The concept of thermal energy is fundamental to thermodynamics, the branch of physics that deals with heat and its relation to other forms of energy and work. It plays a crucial role in understanding various natural phenomena and technological applications, from weather patterns to the operation of engines. While often used interchangeably with "heat" in everyday language, in physics, heat specifically refers to the transfer of thermal energy.
