conduction is transfer of energy due to direct contact, convection is due to density differences
Convection
Both the lava lamp and the Earth's mantle involve convection currents. In a lava lamp, heated wax rises and cools, creating a circulating motion. Similarly, in the Earth's mantle, heat from the core causes molten rock to rise, cool, and sink back down in a continuous cycle due to convection.
convection
Convection currents rese and sink through the mantle and the liquid outer core. In Earth's mantle, large amounts of heat are transferred by convection currents. Heat from the core and the mantle itself causes convection currents in the mantle.

Coduction and convection.
# Coduction # Radiation # Convention # Latent heat # Heat pipes # I learned that convection currents transfer heat throughout the troposphere. (part of the atmosphere)
because they bothhave heat transer
coduction
I think you mean convection and conduction. The first is the transfer of energy through a fluid and the second through a solid. The third way, through a vacuum, is radiation.
Conduction, convection, and radiation are all methods of heat transfer. They are alike in that they involve the movement of heat energy from one object to another. However, they are different in terms of the mechanisms involved: conduction transfers heat through direct contact between objects, convection transfers heat through the movement of fluids, and radiation transfers heat through electromagnetic waves.
Convection is similar in liquids and gases because both involve the movement of particles due to differences in temperature. In both cases, warmer particles rise while cooler particles sink, creating a circular flow of fluids to transfer heat.
Conduction, Convection, and radiation are all ways that heat can be transferred between 2 objects. Conduction is transfer by direct contact like when you cook something on the stove. Convection occurs when heat is transferred by movement like in the Earth's mantle. Radiation occurs when waves are used to transfer heat like sunlight.
Convection
Yes. Convection is a type of energy and a convection current is, well, the phrase for its currents. So yeah, convection and convection current are the same.
Yes, you can use foil in convection ovens and regular ovens alike (despite the different names all ovens are convection ovens, ovens labeled convection ovens are just faster). However, NEVER and I mean NEVER use foil in a microwave. Then it will go BOOOOOOOOOOMMMM!!!!!!!My Oster convection oven manual has a safety warning regarding foil: "Do not cover the oven tray with metal foil. This will cause overheating of the appliance."
The scientific name for convection is "convection."
