The right answer is a. The air above a wildfire.
Three methods allow the applicabe thermal transfer to heat the water.
CONDUCTION HEATING:
* The principle of conduction is probably the simplest heating system to understand.
* This process is based on a heat transfer by the contact between two media of different temperature.
* One hot element will warm another element when they come into contact.
* For example, when you walk on a heated floor, the heat of the floor is directly transmitted to your feet.
CONVECTION HEATING:
* A convector uses the movement and circulation of molecules to transmit heat.
* Radiators that operate through the convection process suck the air and then heat it with an electric heater.
* This air is then blown into the room to warm the surrounding air.
RADIANT HEATING:
* Radiation is a process that transmits heat by waves.
* Indeed, waves are emitted naturally by all objects.
* The hottest elements transmit their heat to the colder elements by these waves. We talk about radiation.
* A radiator that uses this principle generally heats a plate that will transmit heat into the ambient air through the radiation process.
