It would be convection. Convection occurs when heat is applied to a fluid.
Alternating current flows through a flat iron.
probably some kind of heat source, like a hotplate and patience
A thermal energy diagram, also known as a heat flow diagram, illustrates how heat energy flows through a material like rock, showing the temperature changes and distribution within the material. It demonstrates how heat affects the rock by indicating areas of heat gains and losses, as well as the distribution of thermal energy within the rock material.
In a hair dryer, electrical energy is transformed into heat energy. The electricity flows through a resistor or coil inside the hair dryer, which generates heat due to resistance, and this heat is then used to dry and style the hair.
Artesian springs form where pressurized water flows through cracks in cap rock.
The energy transforms from electrical energy to heat energy in an electric blanket. When the electric current flows through the wires in the blanket, resistance in the wires produces heat, which warms the blanket.
solar heat travels in the form of radation waves
A metal
Heat through radiation
Whenever some kind of liquid is involved in cooking food, it is being prepared with a "moist-heat method." When you boil eggs, steam hot dogs, or stew beef, you are taking advantage of moist-heating - you are letting the heat travel through the liquid to the food.
When your hand is on a heat pad, heat transfer is occurring through conduction. This is because the heat from the pad is being directly transferred to your hand through physical contact.
The heat transfer process exemplified by heat traveling through a pan to warm food is known as conduction.
