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.
What transfer of energy naturally occurs between objects?
If two objects of different temperature are brought into contact, internal energy is transferred via heat. If two objects collide, kinetic energy is transferred between them.
What type of heat transfer occurs when two things are touching?
Yes, it is called transfer by conduction.Transfer by radiation requires no contact and transfer by convection requires contact through an intermediate moving fluid.
What 3 ways does the heat move?
Convection, flowing through a liquid or a gas, Conduction, a transfer that occurs between the contact between two objects of different temperatures, or Radiation, where heat is emitted from the surface of an object.
What is the transfer of heat by conduction?
Transfer of heat by conduction is when transfer of heat occurs through touch. Vibrating atoms come in contact with neighboring atoms transferring some of their energy (heat).
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.
How is the energy transfered when the object are in contact?
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.
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.
What transfer of energy naturally occurs between objects?
If two objects of different temperature are brought into contact, internal energy is transferred via heat. If two objects collide, kinetic energy is transferred between them.
What force occurs when objects come into contact?
Friction.
When does Heat transfer occurs in liquid and gasses?
Heat transfer occurs whenever two or more objects of different temperatures are in contact with each other. Spilling hot water on yourself causes heat transfer from the water to you. When you drive your car the hot engine and radiator transfer heat to the surrounding air in order to cool the engine.
When Heat transfer that occurs when molecules come in contact with one another is?
Conduction.

What is the transfer of heat that occurs when particles move between objects or areas of different temperature?
convection
Describe how two objects in direct contact transfer heat?
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.

How radiation and convection is alike?
Conduction, Convection, and radiation are all ways that heat can be transferred between 2 objects. Conduction is transfer by direct contact like when you cook something on the stove. Convection occurs when heat is transferred by movement like in the Earth's mantle. Radiation occurs when waves are used to transfer heat like sunlight.
