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. the particles are known as quanta.
That is called conduction.
Radiation does not need particles to transfer heat.
Heat transfer by movement of particles from one part of a fluid to another is called convection.
is this true or false conduction is heat transfer by direct contact of particles of matter

Radiant heat does not require particles. It involves light in the infrared range.
Heat Radiation does not need a medium (particles of matter).
Convection
Yes, heat can transfer by the mode of radiation.
No,the transfer of heat by the movement of heated fluid is called convection.
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).
