What is heat transfer by convection
{"Image DocumentName": "What is heat transfer by convection?", "Image ImageDescription": "Heat is transferred through a substance through currents. This occurs in fluids (liquids AND gases) Convection currents are caused by heating of a liquid or gas, the liquid or gas rises, then cools and falls. This occurs in the mantle of the earth. And in the atmosphere. Most of our weather patterns are the result of convection currents in the atmosphere.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
