Convection
Convection heat transfer occurs in fluids and gases when warmer particles rise and cooler particles sink, creating a circular motion that transfers heat. This process is driven by differences in density caused by temperature variations within the fluid or gas.
The transfer of heat by circular motion or movement is called convection. In this process, hot fluid or gas rises, while cooler fluid or gas sinks, creating a circular flow that transfers heat from one location to another. This mechanism is commonly observed in fluids like air or water.
Wrong, transfer of heat by conduction does take place in fluids.
Heat transfer by fluids can occur through conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between molecules, convection is the transfer of heat by the movement of fluids, and radiation is the transfer of heat through electromagnetic waves.
Convection currents are vertical circular movements of fluids that transfer energy due to changes in density.
The term for the vertical circular movements of fluids due to changes in density is convection. This process is driven by variations in temperature and results in the transfer of heat energy.
Convection is the type of heat transfer that mainly occurs in fluids, such as liquids and gases, where the heated material rises and the cooler material sinks, creating a circular flow.
Wrong, transfer of heat does take place in fluids. In fact it can take place more efficiently in fluids than in solids because convection is possible in fluids.
Heat transfer by Brownian motion takes place only in fluids (liquids, gases, and plasmas).
Fluids.
The term for these vertical circular movements of fluids is convection. It occurs when warmer, less dense fluids rise and cooler, denser fluids sink, creating a cycle of movement that transfers energy within the fluid.
