In which method of transmission of heat, particles of matter do not move on their own from one place to another?
In conduction, particles of matter do not move on their own from one place to another. Instead, heat is transferred through direct contact between particles. The particles vibrate and transfer energy without significant movement.

In the method of transmission of heat known as conduction, particles of matter do not move on their own from one place to another. Conduction involves the transfer of heat through direct contact between particles in a material. When one part of a solid object is heated, the particles in that region vibrate more vigorously. These vibrations are passed along to neighboring particles, transferring energy from the hotter region to the cooler region. However, the particles themselves do not move significantly from their positions; rather, it is the energy that is transmitted through the material.
In contrast, convection involves the actual movement of fluid particles (liquids or gases) from one place to another, carrying heat with them. Radiation does not require any medium and involves the transfer of heat through electromagnetic waves.
Therefore, the correct answer is [A] Conduction, as it is the method where particles do not move on their own from one place to another.
