There are three ways in which heat can travel.
1. Conduction
2. Radiation
3. Convection
The factor that is necessary for the flow of heat from one object to another is that the two objects must have different temperatures. Heat always "flows," or moves, from the hotter object to the cooler one, unless there is some sort of external agent doing work.
There are three different ways for heat to flow from one object to another: conduction, convection and radiation. Conduction involves heat transfer through atoms bumping into each other. Convection, which happens in air and fluids, takes it a step further. The initial heat transfer is through conduction, but then a loop forms with warm areas rising and cool areas falling, creating a circular effect called a "convection cell." In heat radiation, thermal equilibrium means that particles are absorbing the same amount of radiation from their surroundings that they are radiating out themselves, so nothing changes. Heat transfer occurs when particles are emitting more radiation than they are absorbing from their environment.
