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.
What else can I help you with?
What do you call the space in between the objects in a painting?
It is called Negative Space.
What is the transfer of heat by contact called?
Conduction.

The transfering of pollen between plants is called?
the transfer of pollen grains is called pollination. I the transfer of pollen is from the anther to the stigma of the same plant it is known as self pollination, whereas if the transfer of pollen is from the anther of one flower to the filament of a different flower, it is termed as cross pollination

When two objects are touching and transfer heat is called what?
When two objects are touching and transfer heat, it is called conduction. Conduction is the transfer of heat energy through direct contact between particles of different temperatures.
What is heat energy moving between two touching objects called?
The transfer of heat energy between two touching objects is called conduction. This process occurs as a result of direct contact between the objects, leading to the transfer of thermal energy from the object with higher temperature to the one with lower temperature.
When two objects are touching and transfer heat it is called what?
Conduction.
When two objects are touching and transfer heat is called?
Conduction
When two objects are touching and transfer heat it is called?
Conduction
What is a force between two moving objects that are touching?
The force between two moving objects that are touching is called kinetic friction. Kinetic friction acts opposite to the direction of the motion of the objects and resists their motion. It is caused by the interaction between the surfaces of the two objects.
Heat energy moving between two touching objects is called?
conduction
Do hot objects move heat to other objects without touching them?
Yes, hot objects can transfer heat to other objects through a process called radiation. This type of heat transfer occurs without the objects needing to be in direct contact with each other.
What is the process that involves the transfer of heat directly between two objects in contact?
The process that involves the transfer of heat directly between two objects in contact is called conduction.
What is the force exerted only when two objects are touching?
The force exerted only when two objects are touching is called friction. Friction occurs as a result of the resistance between the surfaces of the objects when they move against each other.
what is it called when The transfer of thermal energy by direct contact between objects?
Conduction.
What is The transfer of energy to one object touching another?
The transfer of energy from one object to another through direct contact is called conduction. This process allows heat or electricity to be passed between objects that are in physical contact with each other.
