Best Answer

When energy is transfered to a system of particles, the system is said to be heated. The particles absorb this energy and convert it to kinetic energy, causing their translational motions to increase. Temperature is a measure of the average translational motion of particles. Hence, heating an object causes the particles that make up that object to move more and these motions manifest themselves in what we know as the temperature of the object. In fact in the absolute temperature scale of thermodynamics a zero temperature corresponds to a system of particles in which there is no motion.

Radiation does not need particles to transfer heat.


What is the transfer of heat by the movement of particles from one part of a fluid to another?

Heat transfer by movement of particles from one part of a fluid to another is called convection.

Which type of heat transfer does not involve particles?

Radiant heat does not require particles. It involves light in the infrared range.


Which type of heat transfer can happen even if there are no particles of matter?

Heat Radiation does not need a medium (particles of matter).


What is the transfer of heat by the movement of particles in fluids?

Convection


Can heat travel without particles?

Yes, heat can transfer by the mode of radiation.


What method of heat transfer is known as conduction?

No,the transfer of heat by the movement of heated fluid is called convection.


Is conduction a heat transfer by direct contact of particles of matter?

Yes, whereas convection heat transfer is the transfer of heat via a liquid, and radiative heat transfer occurs through empty space (like the heat you feel from the sun).
