the heat is transferred by direct contact of particles of matter
Heat is transferred through kettle walls primarily by conduction. When the kettle is heated on a stove, the heat from the flame is transferred to the bottom of the kettle through conduction. This heat is then transferred to the rest of the kettle through the metal walls by conduction as well.
Conduction.
Conduction is the type of heat transfer that occurs when heat is transferred through a substance. In conduction, heat moves from higher to lower temperature regions within the substance.

Heat is transferred through contact between molecules.
The heat used for frying is transferred to the pan by conduction and radiation and is transferred to the fried object by conduction through the oil.
Heat can be transferred through conduction, where heat is transferred through direct contact between materials; convection, where heat is transferred through the movement of fluids or gases; and radiation, where heat is transferred through electromagnetic waves without the need for a medium.
Particles is one thing, waves is something else. Heat transferred by the motion of particles can be conduction or convection. Heat transferred by electromagnetic waves is radiation.

Conduction
Heat can travel through conduction, convection, and radiation. In conduction, heat is transferred through direct contact of molecules. In convection, heat is transferred through the movement of fluids such as air or water. In radiation, heat is transferred through electromagnetic waves.
