Answer:

the process in which heat moves through a gas or a liquid as the hotter part rises and the cooler, heavier part sinks

the process in which heat moves through a gas or a liquid as the hotter part rises and the cooler, heavier part sinksगैस या द्रव में ताप फैलने की प्रक्रिया जिसमें गरम भाग ऊपर उठता है और ठंडा भाग नीचे आता है; संवहन |

संवहन ऊष्मा के स्थानान्तरण या संचरण की एक विधि है किसी तरल पदार्थ में अणुओं के समग्र स्थानान्तरण द्वारा ऊष्मा का लेन-देन होता है। ठोसों में संवहन सम्भव नही है किन्तु तरल पदार्थों में संवहन ऊष्मा के अन्तरण की एक मुख्य विधि है। संवहन द्वारा द्रव्यमान का भी स्थानान्तरण होता है।

Convection is the transfer of heat by circulating it through air or liquids. A heat source at the bottom of the balloon heats the air molecules around the flame, and those molecules rise. Warmer air is less dense than cold air, so as the warm air rises the molecules spread out.
