Two objects must be touching and it has to transfer heat
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.
contact force:when two objects are in contact with each other it is called contact force.non-contact force:when two objects are not in contact with eachover
contact force:when two objects are in contact with each other it is called contact force.non-contact force:when two objects are not in contact with eachover
If those two objects are in contact with each other, they will come to thermal equilibrium, at a temperature some place between the original temperature of the two objects. The actual final temperature will depend on the specific heat capacity of each object, the mass of each object and the temperature of each object.

FRICTION
false
No.
The region of contact refers to the area where two objects are touching each other. It is important in physics for analyzing forces and interactions between objects. The region of contact can vary in size and shape depending on the objects involved and the nature of their interaction.
Friction
if you are talking about contact force, then you are correct. but if you are talking about some other external force,then the answer will be no. because frictional force only depends on the contact force between any two objects.
