1. The act or process of conveying; transmission.
2. Physicsa. Heat transfer in a gas or liquid by the circulation of currents from one region to another.
b. Fluid motion caused by an external force such as gravity.
3. Meteorology The transfer of heat or other atmospheric properties by massive motion within the atmosphere, especially by such motion directed upward.
The three main types of convection are natural convection, forced convection, and mixed convection. Natural convection occurs due to density differences caused by temperature variations. Forced convection involves the use of external means like fans or pumps to enhance fluid movement. Mixed convection combines both natural and forced convection mechanisms.
A convection current, however, this can also occur with gases.
Convection is the transfer of heat through a fluid (such as a gas or liquid) caused by the movement of the fluid itself. It occurs when warmer, less dense fluid rises and cooler, denser fluid sinks, creating a cycle that transfers heat energy. This process is commonly observed in weather patterns and the movement of heat within the Earth's mantle.
Another word for convection is "circulation."
Convection conductors are materials that are good at transferring heat through convection. Convection is the transfer of heat through the movement of a fluid (liquid or gas). Materials like metals, which have high thermal conductivity, are often good convection conductors.
the transfer of heat by currents within a liquid or gas
A convection boundary is the boundary at which heat or energy is transferred through convection, which is the movement of fluids (liquids or gases) due to temperature differences. This boundary marks the area where the fluid in contact with a solid surface gains or loses heat through convection.
Cooking by dry heat, as in a convection oven.
The transfer of heat through a fluid (liquid or gas) caused by molecular motion.
where the temperature is dropping or increasing! Edit: Convection is the rising and falling of heated gas.
The upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.
Convection
Yes. Convection is a type of energy and a convection current is, well, the phrase for its currents. So yeah, convection and convection current are the same.
In social studies, convection refers to the transfer of heat through the movement of fluids, such as air or water, due to differences in temperature. This process plays a significant role in shaping weather patterns and ocean currents, influencing how populations interact with their environments.
The scientific name for convection is "convection."
That sounds like a definition of "conduction" - as opposed to convection or radiation, which are other modes of heat transfer.
The three main types of convection are natural convection, forced convection, and mixed convection. Natural convection occurs due to density differences caused by temperature variations. Forced convection involves the use of external means like fans or pumps to enhance fluid movement. Mixed convection combines both natural and forced convection mechanisms.
