संवहन (Convection Meaning in Hindi)

Convection (Meaning in Hindi) संवहन

(Definition in Hindi) तापमान में अन्तर के कारण गैसों या तरल पदार्थों का संचलन।

In thermal convection, some of a fluid (liquid or gas) receives heat. It thus warms, becomes less dense and rises. It is continuously replaced by colder fluid which is subsequently heated and thus also rises, forming a convection loop or convection current. Convection stops when the temperature differences between different parts of the fluid are too small to create any movement.
