yes. btw, that's not a question.
The transfer of energy between two objects is referred to as heat transfer. It is always called heat transfer, regardless of what kind of energy is being transferred.HeatThermal energy.yes. btw, that's not a question.
Because transfer of heat requires particles, so solid objects will be better at conducting heat than gas.
The transfer of energy between two objects at different average thermal kinetic energies (temperatures) is referred to as heat transfer. It is always called heat transfer, regardless of what kind of energy is being transferred.
Heat is not the transfer of thermal energy. Heat is the thermal energy. What drives itacross a boundary between substances or objects is a difference in their temperatures.
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.
It depends on the respective temperatures of the bodies.
when two cold objects are rubbed against with each other...
wheasease cw: they approach in temperature.
That sounds like a definition of "conduction" - as opposed to convection or radiation, which are other modes of heat transfer.
Heater is energy. Energy transfers from the higher energy unit to the lower energy unit, until they reach equilibrium. Equilibrium is when both objects contain the same amount of energy, therefore it is impossible for any to transfer between each other. The basic conditions for no heat transfer between two objects is for them to be the same temperature. To keep them at that same temperature, they would have to be floating in a perfect vacuum chamber so they had no contact with matter whatsoever. They would have to be shielded from infrared heat energy as well.
Conduction, convection, radiation Conduction: The transfer of energy by collisions between the atoms and molecules in a material. Convection: Transfers heat when particles move between objects or areas that differ in temperature. Radiation: The transfer of energy by waves.
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.
conduction's heat energy is sometimes transfered between two different objects. But convection's heat energy is transfered through the particles in a liquid or gas move.
Temperature is a measure of the amount of heat energy an object has.As per the second law of thermodynamics, heat flows from hotter objects to colder objects. The bigger the difference in temperature, the more heat flows.
Since different objects have different heat conductivity and different temperatures and heat capacities, the time can vary without limit.
It's not. A difference in temperature is required in order to drive the transfer of heat.
A transfer of heat (H) energy does not occur without a temperature differential. If the two objects had different amounts of H then a transfer would indeed occur. In this case heat would flow from a higher to lower temperature object.
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.
Thermal energy is a specific type of energy that all objects have. Heat refers specifically to the TRANSFER of this type of energy. I believe this is similar to the difference between "mechanical energy" and "work" (where "work" refers to the transfer of such energy). However, the two terms are actually often used interchangeably.
No, energy will transfer between any adjacent bodies, moreover, a medium is not necessary for energy to transfer between objects at all. That would be a little thing called radiation.
"Heat" basically refers to the transfer of thermal energy. And yes, such energy will flow from hotter to colder objects.

Temperature is a measure of the heat energy of objects, and heat is the energy transferred from a high temperature location to a low temperature location.When two objects are in contact, heat always flows from the warmer object to the cooler object by conduction, until thermal equilibrium is established and the heat transfer stops (becomes the same in either direction). The transfer of heat continues as long as there is a difference in temperature between the two points.
No, there will only be a spontaneous transfer of heat if the objects are at different tempratures.No, there will only be a spontaneous transfer of heat if the objects are at different tempratures.No, there will only be a spontaneous transfer of heat if the objects are at different tempratures.No, there will only be a spontaneous transfer of heat if the objects are at different tempratures.
Strictly speaking, heat is the transfer of energy from objects of differing temperatures. To have heat energy, an item must be of a different temperature than its environment.
