Causes of Enlarged Prostate. BPH is a benign (non-cancerous) enlargement of the prostate that is extremely common in older men. It is generally thought to be caused by years of exposure to male hormones like testosterone. While BPH is benign and cannot spread to other parts of the body, it can cause problems.
1 Conduction is the transfer of thermal energy through direct contact between particles of a substance, without moving the particles to a new location.
Energy can be transferred by conduction, convection, evaporation and condensation. All these processes involve particles. Conduction. Is the movement of thermal energy through a material without the particles in the material moving. Glass, wood and plastic are all poor conductors of heat. Heat is the kinetic energy of particles as they vibrate. If we heat the particles at one end of a material the particles at that end vibrate more (have more kinetic energy) and bump into the neighbouring particles which causes them to vibrate more. They collide with their neighbours and so the energy is passes from one particle to another through the material.
