| Description: (a) Heat supplied by the heating coil warms the water at the bottom of the pot. The heated water consequently expands, decreasing its density. This lower-density water rises (like bubbles in soda) and transfers its heat to the cooler surroundings. When the hot, rising water gets to the top of the pot, it loses a lot of heat into the room, becomes denser, and sinks back to the bottom of the pot to repeat the process Picture Stats: Views: 656 Filesize: 250.91kB Height: 895 Width: 1350 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=15968 |
