Radiation is a heat transfer that can occur in a vacuum because it does not rely on the presence of a medium to propagate. It is the transfer of heat through electromagnetic waves, such as infrared radiation.

What type of heat transfer occurs in only liquid and gases?

Convection is the type of heat transfer that occurs in only liquids and gases. It involves the transfer of heat through the movement of the fluid molecules due to differences in their density and temperature.


What type of heat transfer occurs only in fluids?

Heat transfer by Brownian motion takes place only in fluids (liquids, gases, and plasmas).


What is the only type of heat transfer that occurs in fluids?

convection


What type of heat transfer occurs only in gasses or liquids?

Convection is the type of heat transfer that occurs only in gases or liquids. It involves the movement of the heated fluid itself, which carries heat energy from one place to another.


What energy transfer only occurs in fluids?

Convection is an energy transfer process that occurs only in fluids like liquids and gases. It involves the transfer of heat through the movement of the fluid itself, which results in the circulation of the fluid and the transfer of heat from one place to another.


Does heat transfer from one objects to another with the same temperature?

yes


Which type of heat transfer occurs in the form of waves?

Radiation is the type of heat transfer that occurs in the form of waves. This transfer of heat can occur through empty space and does not require a medium. Examples include sunlight and heat transfer from a fire.


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 is the basic theory of heat transfer?

Heat transfer occurs by convection, conduction and radiation. In conduction, heat is transferred through collision of rapidly moving molecules. It is only through successive collision of molecules that heat transfers through an object.


How is heat transfer by radiation different form heat transfer by convection and conduction?

Radiation requires neither contact (through which conduction transfers heat) nor mass flow or movement (through which convection transfers heat). Only radiation can take place in a vacuum. Convection and conduction both require a material medium for the heat transfer to occur. Only radiation can transfer thermal energy through the vacuum of space.


What form of energy transfer occurs when heat is transferred from one object to another?

The form of energy transfer that occurs when heat is transferred from one object to another is called conduction.


How does one-dimensional heat transfer differ from two-dimensional heat transfer?

One dimensional heat transfer is when the temperature varition is in one direction only while two dimensional heat transfer is when temperature varies mainly in two directions (i.e x,y or r,z).
