Heat does not exist at the level of atoms, at the level of the atom its kinetic energy; which is only observed as heat at the macroscopic/bulk level.
Atoms with more kinetic energy bounce harder against other atoms, transferring more kinetic energy to those atoms. This has two effects at the macroscopic/bulk level, where heat is observed:
- direct transfer of kinetic energy results in diffusion of heat, called conduction
- kinetic energy pushes the atoms further apart causing a reduction in density, enabling a process called convectionif the liquid is accelerating or in a gravitational field
What else can I help you with?
What fluid instead of water can be used as a heat transfer in domestic heating system?
Liquid sodium
Transfer of heat by hot liquids and gases?
Convection is the transfer with in the fluid. If a container of hot liquid is touching something then it is conduction. If the heat is travelling through the air then it is radiation.
What does convection mean in science terms?
convection is the transfer of heat in a liquid or gas by thermal energy from one part of a fluid to another. ;0)
What is a thermal conduction?
heat transfer from one molecule to another -apex
What method of heat transfer is known as conduction?
No,the transfer of heat by the movement of heated fluid is called convection.
How does Transfer of heat energy in a liquid?
Heat transfer in liquids can occur through conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between molecules within the liquid. Convection involves the movement of the liquid itself, carrying heat energy through the fluid. Radiation is the transfer of heat through electromagnetic waves.
Is the transfer of heat by moving liquid or gas called conduction?
No, the transfer of heat by moving liquid or gas is called convection. Conduction is the transfer of heat through a material without the movement of the material itself.
What is the transfer of heat by a liquid or gas?
convection
What is the transfer of heat within a liquid?
when the temperature of the liquid is the same throughout.
What three forms of heat energy can be transferred from a liquid in a thermos?
Conduction: heat transfer through direct contact between the liquid and the thermos. Convection: heat transfer as the liquid circulates within the thermos. Radiation: heat transfer through electromagnetic waves between the liquid and the walls of the thermos.
What is the term for heat transfer because of the heat of gas?
Convection is the transfer of heat through the movement of a fluid, whether liquid or gas.
What is heat transfer that does not cause a temperature change?
Heat transfer that does not cause a temperature change is called latent heat transfer. This occurs when heat is absorbed or released during a change in state (solid to liquid, liquid to gas) without changing the temperature of the substance.
What is the transfer of heat by the motion of liquid and gasses?
CONVECTION
Is evaporation a method of heat transfer?
Yes, evaporation is a method of heat transfer. It involves the transfer of heat from a surface to a liquid that evaporates, taking the heat with it. This process cools the surface.
Heat convection what is?
Convection is the transfer of heat by circulation through a gas or liquid.
What type of heat transfer uses a gas or a liquid to transfer the heat?
Convection is the heat transfer process that uses a gas or liquid to transfer heat. This occurs as the material heats up, becomes less dense, and rises, displacing cooler material that then heats up, creating a continuous cycle of heat transfer.
What transfer of thermal energy of a liquid or gas?
The transfer of thermal energy in a liquid or gas occurs through conduction, convection, or radiation. In conduction, the heat is transferred through direct contact between molecules. Convection involves the transfer of heat through the movement of the liquid or gas itself. Radiation is the transfer of heat through electromagnetic waves.
