Convection is an energy transfer process that occurs only in fluids like liquids and gases. It involves the transfer of heat through the movement of the fluid itself, which results in the circulation of the fluid and the transfer of heat from one place to another.
Heat transfer by Brownian motion takes place only in fluids (liquids, gases, and plasmas).
Convection only occurs in fluids. Fluids are gases or liquids.

Convection is the type of heat transfer that occurs only in gases or liquids. It involves the movement of the heated fluid itself, which carries heat energy from one place to another.
Energy transfer occurs when energy is moved from one place to another, or transformed from one form to another. This can happen through processes like conduction, convection, and radiation. The First Law of Thermodynamics states that energy cannot be created or destroyed, only transferred or converted.

Convection is the type of heat transfer that mainly occurs in fluids, such as liquids and gases, where the heated material rises and the cooler material sinks, creating a circular flow.
Convection is the type of heat transfer that can only travel through fluids (liquids and gases) due to the movement of the fluid itself.
Energy transfer in communities occurs through food webs, where energy flows from producers to consumers to decomposers. This transfer follows the 10% rule, where each trophic level retains only about 10% of the energy from the previous level. Energy transfer is crucial for sustaining life within ecosystems and is a key component of the Earth's biogeochemical cycles.
Conduction works well in solids due to the close packing of particles, allowing vibrations to transfer energy efficiently. In fluids, conduction is less efficient because particles are further apart and can only transfer heat through collisions, leading to slower heat transfer rates.
Radiation requires neither contact (through which conduction transfers heat) nor mass flow or movement (through which convection transfers heat). Only radiation can take place in a vacuum. Convection and conduction both require a material medium for the heat transfer to occur. Only radiation can transfer thermal energy through the vacuum of space.
Radiation is the only method of energy transfer that can transfer energy like heat through space.
