Cold convection
WebFeb 27, 2024 · There are three different ways heat can move between objects: conduction, convection and radiation. Conduction occurs when objects are in direct contact with one … WebMay 29, 2024 · Convection. Convection is the movement of warmer areas of a fluid (liquid or gas) to cooler areas of a fluid. The movement can occur naturally or may be forced through mechanical means. Natural convection occurs in fluids due to the fact that hot fluids will rise through cold fluids since they have a lower density.
