On a molecular scale, thermal energy is the kinetic energy of individual particles. In a liquid, this thermal energy is transferred to nearby atoms by collisions; a high-speed particle in the liquid collides with a lower-speed particle, transferring some kinetic energy from the high-speed particle to the low-speed particle. When this happens with a large number of particles, thermal energy transfer results.

When rapidly vibrating atoms collide with slowly vibrating atoms causing a transfer of heat?
Heat
How does an atom in a liquid transfer heat?
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 conductionkinetic 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
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.
Is heat the transfer of atoms between substances of different temperatures?
No, heat is the transfer of energy between substances due to a temperature difference. It flows from a hotter object to a colder one, raising the temperature of the latter. Atoms themselves do not transfer between substances during heat transfer.
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.
