Which involves transfer of heat by the physical movement of the material?
Convection is the process that involves the transfer of heat by the physical movement of a material, typically a fluid like air or water. This movement occurs due to differences in temperature, causing warm fluid to rise and cool fluid to sink, creating a cycle of heat transfer.
What is the transfer of energy by circulation or movement of gas called?
The transfer of energy by circulation or movement of gas is called convection. This process involves the movement of the gas molecules to carry energy from one place to another.
Movement of heat in a liquid or gas?
Heat can be transferred in a liquid or gas through conduction, convection, or radiation. Conduction is the transfer of heat through direct contact between molecules. Convection involves the movement of the heated material itself, causing a transfer of heat. Radiation is the transfer of heat through electromagnetic waves.
What is it called the movement of material due to differences in density?
The movement of material due to differences in density is called convection. This process involves the transfer of heat through the movement of fluids such as air or water.
Which of the following methods of heat transfer involves the actual physical movement of high temperature molecules to region of low temperature?
Convection involves the physical movement of high-temperature molecules from a region of high temperature to a region of low temperature. This transfer of heat occurs through the mixing of fluids or gases.
Heat transfer that involves mass movement is?
Convection is the process whereby heat is transferred by the mass movement of molecules from one place to another.
State and discuss the modes transfer of heat?
The modes of transfer of heat are: # Conduction # Convection # Radiation In Conduction, heat is transferred along the material by the vibration of molecules. The molecules, however, don't actually move from their positions. It is usually seen in solids only. Heat transfer in Convection is by actual movement of material molecules. It is seen in liquids and gases. Radiation is the mode of transfer which does not need any material medium. The transfer of heat is done by electromagnetic waves.
What type of heat transfer involves molecules bumping into each other?
Conduction involves the transfer of heat through direct contact between molecules, where the molecules bump into each other and transfer kinetic energy.
How does heat transfer to one material to another?
it transfers from heat flow
Which method of heat transfer causes actual movement of material?
Both conduction and convection. Conduction involves the small movements of individual particles, convection can be on a much larger scale with a hot liquid or gas rising and a cool liquid or gas dropping.
What is the process of heat transfer in gases and liquids?
Heat transfer in gases and liquids occurs primarily through conduction, convection, and radiation. Conduction involves the transfer of heat through direct physical contact between molecules. Convection involves the transfer of heat through the movement of fluids. Radiation involves the transfer of heat through electromagnetic waves.
Which is the transfer of heat through a material without movement of the material itself?
Conduction is the transfer of heat through a material without movement of the material itself. This process occurs due to direct contact between particles in the material, where faster-moving particles transfer heat energy to slower-moving particles.
