When a cold object and a hot object are in direct contact (touching) heat will be transferred through thermal conduction.
Normally, heat transfer processes are categorized as thermal conduction, radiative transfer or convection.
Heat transfer through thermal conduction is the direct transfer of kinetic energy from one molecule to the nearby molecules. Because temperature is directly proportional to kinetic energy, interactions between neighboring particles exchange energy and that exchange energy gradually works it way from the higher temperature regions to the lower temperature regions. The process of the temperature becoming the same is called thermal equilibration.
Convective heat transfer occurs in fluids. If a gas, liquid, or other fluid, changes in fluid density change the buoyancy and will cause fluid to flow (a process called convection) and the heat contained in the warmer fluid is transferred to a new location by the physical movement of the fluid.
Radiative transfer occurs when a hot object radiates electromagnetic energy. While the sun is an obvious source of electromagnetic energy, it is also generated in smaller amounts by any object. The hotter objects radiate more electromagnetic energy and the cooler objects absorb it. This radiative transfer is important but not as noticeable usually as the other two. It does occur between objects whether they are in direct contact or not, but is usually so small as not to be important of the objects are touching.

Which kind of heat transfer involves direct contact between the molecules of the hotter object and the colder object?
Conduction involves the direct contact between two objects to transfer heat.
Which type of heat transfer is by direct contract?
The type of heat transfer by direct contact is called conduction. Heat is transferred through a solid material or between two objects in direct contact with each other. This occurs as the particles in the material or objects collide and transfer energy to each other.
This type of thermal energy transfer only happens when 2 objects are making direct contact?
"conduction"
The type of energy transfer that takes place between objects in direct contact is called what?
Energy is mainly transferred in the form of heat. So,transfer of heat energy from one body to another by direct contact is called thermal conduction.
What is heat transfer through direct contact called?
The transfer of heat through direct contact is called conduction.
What is the term heat transfer because of direct contact?
Conduction is the term for heat transfer because of direct contact.
What is the transfer of energy as heat between objects that are in direct contact called?
That sounds like a definition of "conduction" - as opposed to convection or radiation, which are other modes of heat transfer.
What is the transfer of heat when to objects are not touching?
convection and radiation heat transfer bot occur without either object being in direct contact with each other.
What is the term for heat transfer of direct contact?
Conduction is the term for heat transfer because of direct contact.
What is meant by conduction heat transfer?
Conduction heat transfer refers to the process of heat transfer between two objects or regions in direct contact with each other. This transfer occurs due to the collision and transfer of energy between the molecules of the objects. It relies on the physical contact and proximity of the objects for heat to be conducted from the hotter object to the cooler one.
The transfer of heat by direct contact?
conduction
The transfer of heat by the direct contact?
Conduction.
