When a fluid is heated, it becomes less dense and tends to rise while cooler fluid sinks to replace it, creating a movement known as convection. This movement helps to transfer heat throughout the fluid by circulating hot and cold regions. The process continues as long as there is a temperature difference driving the fluid movement.
False. Radiation is the transfer of heat energy in the form of electromagnetic waves, while the transfer of heat by the movement of a heated fluid is known as convection.
If the heated fluid is warmer than the fluid around it, it will generally rise due to its lower density. This movement is known as natural convection, where the warmer fluid displaces the cooler fluid and creates circulation in the system.
The circular movement you are describing is called convection. This process occurs when heated fluid rises due to decreased density and is replaced by cooler fluid, creating a continuous circular flow.
Convection is a type of energy transfer that requires a fluid. It involves the movement of heated fluid, such as air or water, to transfer heat energy from one location to another.
Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it.

False. Radiation is the transfer of heat energy in the form of electromagnetic waves, while the transfer of heat by the movement of a heated fluid is known as convection.
When a fluid (liquid or gas) is heated, it expands. The heated fluid is therefore less dense than the fluid around it, so it rises.Colder fluid then sinks down to replace it and this sets up a movement of fluid called a CONVECTION CURRENT.
Heat transfer by the movement of a heated fluid is called _________?
The transfer of heat through the movement of heated fluid under the Earth's surface is called convection. This process plays a key role in the movement of tectonic plates and the generation of geothermal energy.

The circular movement you are describing is called convection. This process occurs when heated fluid rises due to decreased density and is replaced by cooler fluid, creating a continuous circular flow.
Convection currents are driven by differences in temperature and density within a fluid. When a fluid is heated, it becomes less dense and rises, while cooler, denser fluid sinks. This creates a circular motion as the heated fluid rises, cools, and then sinks back down.
Convection is heat transfer by the movement of heated fluids. Heat transfer is the movement of energy from a warmer object to a cooler object.
