Flow of energy quick check
The flow of energy refers to the movement or transfer of energy from one object or system to another. This flow can occur through various processes, such as conduction, convection, and radiation.
Conduction is the transfer of energy through direct contact between two objects or substances. For example, when you touch a hot object, heat energy is transferred from the object to your hand through conduction.
Convection is the transfer of heat energy through the movement of fluids, such as liquids or gases. This can occur through the circulation of air in a room or the movement of water in a pot when it is heated.
Radiation is the transfer of energy through electromagnetic waves. This can occur through the emission and absorption of heat or light energy. For example, the Sun emits radiation in the form of sunlight, which is absorbed by the Earth, warming its surface.
In general, energy flows from areas of higher energy to areas of lower energy, seeking equilibrium. This flow of energy is essential for various processes, such as powering our daily activities, sustaining life on Earth, and driving natural phenomena, such as weather patterns and climate.
