Molecules are constantly in motion. When a collision between two molecules occurs, kinetic energy is transfered.
Conduction
Heat conduction is the transfer of heat energy between two molecules that are in direct contact,
The heat energy is basically transfered by the motion of the molecules in that material, when heat is given to a certain mass then the kinetic energy of the molecules increases, the molecules transfer heat to each other due to which when any material touches that material the molecules of that material transfer their energy to the object that is in contact. But it is important that the first material is a conductor
Density determines how far apart molecules of a material are from one another, i.e. Density is the mass per unit of space. Due to this, density is related to the rate of heat transfer or thermal energy transfer. Thermal energy being transferred relies on the difference in the internal energy of molecules, mostly kinetic energy, as when heat is transferred, these molecules exchange energy by hitting into each other. By doing so, eventually thermal equilibrium is established. Summary - Density is related to the rate of heat transfer between two systems.
Conduction
energy transfer occurs due to random collision of different molecules of the objects with each other,if the objects are of equal energy,there will be no detectable heat transfer,as molecules have same energy,but in between the objects having different heats the energy transfer occurs,due to the random collision of molecules with each other.
Molecules are constantly in motion. When a collision between two molecules occurs, kinetic energy is transfered.
The transfer of thermal energy by molecules bumping into each other is known as conduction. Thermal energy is energy that comes from heat.
