Yes, that's correct! In thermodynamics, heat transfer occurs from a hotter object to a colder object until thermal equilibrium is reached—meaning that both objects attain the same temperature. This principle is based on the second law of thermodynamics, which states that heat naturally flows in this direction unless work is done to move it against this gradient. There are three primary modes of heat transfer: conduction, convection, and radiation.
- **Conduction** involves direct contact between materials.
- **Convection** occurs in fluids (liquids and gases) as warmer parts of the fluid rise and cooler parts sink.
- **Radiation** is the transfer of heat through electromagnetic waves, which can occur in a vacuum (like heat from the sun reaching the Earth).
