In the Sun, the radiative zone, which lies just outside the core, transfers energy primarily through radiation, where photons are absorbed and re-emitted by particles, taking a long time to move outward. In contrast, the convection zone above it transfers energy through convection, where hot plasma rises to the surface, cools, and then sinks back down to be reheated, creating a more efficient and faster energy transfer process.
Radiant energy is heat transferred through electromagnetic waves, such as from the sun or a fire. Convection energy is heat transferred through the movement of fluids or gases, such as warm air rising and cool air sinking. They represent different mechanisms of heat transfer.
The Sun's radiative zone is located between the core and the convective zone, where energy is transferred outward primarily through radiation. In this zone, photons take a long time to move through due to scattering, often taking thousands to millions of years to reach the outer layers. In contrast, the convective zone, which lies above the radiative zone, transports energy through convection, where hot plasma rises, cools, and then sinks, creating a more efficient and quicker transfer of energy. This difference in energy transfer mechanisms leads to distinct behaviors in these two layers of the Sun.
Whether electrons are shared or transferred between two atoms is determined by the difference in electronegativity between the atoms. If the electronegativity difference is small, electrons are shared covalently, while if the difference is large, electrons are transferred to form an ionic bond.
Energy can be transferred through conduction, where heat is transferred via direct contact between objects. Energy can also be transferred through convection, where heat is carried by a fluid like air or water. Lastly, energy can be transferred through radiation, where electromagnetic waves carry energy from one location to another.
Heat is normally transferred to specific areas by means of a 'heat sink' which is usually made of a material with low resistance and high transfer of heat. An example of this can be seen in most computers, the heat sink collects the heat from the processor, and there is (usually) a fan which is near or on the heatsink to remove it from the heat sink, effectively lowering the temperature of the processor.

Conduction is the transfer of heat through direct contact between particles, while convection is the transfer of heat through the movement of fluids (liquids or gases). Thermal energy refers to the internal energy of an object due to its temperature, which can be transferred through conduction or convection.
One key difference is that in a radiation zone, energy is primarily transferred through electromagnetic radiation, while in a convection zone, energy is transferred through the movement of hot gas or liquid. Radiation zones are generally more stable and characterized by slow energy transfer, while convection zones are more dynamic and turbulent.

Thermal energy that is transferred is known as heat. It can move from one object to another due to a difference in temperature between the two objects. This transfer of heat can occur through conduction, convection, or radiation.
Heat energy is a form of energy that is transferred between objects due to a temperature difference. It can be transferred through conduction, convection, or radiation. Heat energy is responsible for changing the temperature of an object or substance.
The main difference between convection and microwave cooking methods is the way heat is transferred to the food. Convection cooking uses hot air to cook food evenly, while microwave cooking uses electromagnetic waves to heat food quickly from the inside out.
Earth's heat is transferred by convection, which is the movement of heat through a fluid due to differences in temperature. It is also transferred by conduction, which is the direct transfer of heat through a material due to a difference in temperature between two points.
