Answer:
Thermal energy can be transferred globally through various methods, including conduction, convection, and radiation.
Conduction is the transfer of thermal energy through direct contact between objects. When two objects with different temperatures are in direct contact, heat will flow from the warmer object to the cooler object until both objects reach thermal equilibrium.
Convection is the transfer of thermal energy through the movement of fluids or gases. When a fluid or gas is heated, it becomes less dense and rises, while cooler fluids or gases sink. This creates circulation patterns that can transfer heat from one location to another.
Radiation is the transfer of thermal energy through electromagnetic waves. All objects with a temperature above absolute zero emit electromagnetic radiation, and this radiation can be absorbed by other objects, transferring heat.
Thermal energy can also be transferred globally through the use of heat pumps, which use electricity to move heat from one location to another. Heat pumps can be used to heat buildings in cold climates and to cool buildings in hot climates.
