Convection
it's because of heat transfer into convection .
it is conduction
This is an example of conduction, where heat is transferred through direct contact between the burner and the pan. The burner heats the bottom of the pan, which in turn heats the food inside.
immersion heater because heat is sent directly to the object and it heats faster
A tankless water heater uses less electricity compared to a traditional water heater because it only heats water when needed, whereas a traditional water heater continuously heats and stores water.
An iron uses conduction as the method of heat transfer. When the electric coil inside the iron heats up, it transfers the heat to the metal plate on the bottom, which then heats up the fabric through direct contact.
it heats water
Because air expands when it heats up. Due to this expansion, warm air is less dense than cold are, and naturally rises. The name for this effect is (natural) convection.
"A water heater stores water in a tank and heats the water with a flame at the bottom. The hot water rises to the top of the tank, while the colder water falls to the bottom near the heat source." A water heater is simply a tank of water with a heat source at the bottom. It can be set to a certain temperature and is dispersed throughout the home through the water infrastructure.
This process involves conduction heat transfer, where heat is transferred from the burner to the pot through direct contact. The burner heats the metal surface of the pot, which then transfers the heat to the contents inside through conduction.
it heats water
A space heater heats a room by transferring heat through convection, radiation, or a combination of both. Convection heaters warm the air, which rises and circulates around the room. Radiant heaters emit infrared radiation that directly heats objects and people in its path.
