When air moves, energy is transferred through the kinetic energy of the moving particles. As air particles gain speed and momentum, they carry and transfer energy to surrounding particles through collisions and pressure differences. This energy transfer can manifest as wind or airflow, impacting the environment and potentially performing work.
The energy transferred in this scenario is thermal energy, which moves from the hot pan to your hand, resulting in a sensation of heat.

In an electric fan, energy is transferred by converting electrical energy into mechanical energy. When the fan is turned on, electricity powers the motor, causing it to rotate the blades which then push air around. This mechanical energy from the motor is what moves the fan blades and creates the airflow.
When energy moves from one form to another, it is said to be "transferred" or "converted".
Energy can be transferred through conduction, where it moves through direct contact between objects, through convection, where it involves the movement of fluids like air or water, and through radiation, where energy is transmitted through electromagnetic waves.

When energy is transferred to air, the molecules in the air become more excited. The energy causes the molecules to move around more than they did before, which could cause an increase in temperature, among other things.
When energy is transferred to air, the particles in the air gain kinetic energy and move faster, increasing their temperature. This can cause the air to expand and become less dense, leading to changes in pressure and volume.
Thermal energy is transferred from areas of higher temperatures to areas with lower temperatures.
When you let a balloon go, the stored potential energy in the stretched rubber is converted into kinetic energy as the balloon moves through the air. Some energy is also transferred as sound, heat, and air turbulence.
It is called convection. Heat energy is transferred through the movement of air or water molecules, causing warm air to rise and cool air to fall, creating a continuous circulation of heated air in a room.
Heat energy is transferred from warmer objects to cooler objects.
