What happens when the heat source is removed from a convection current?

What happens when the heat source is removed from a convection current?

Convection currents continue as long as heat is added. What happens after the heat source is removed? Without heat, the convection currents will eventually stop when all of the material has reached the same temperature. The heat source for these currents is heat from Earth’s core and from the mantle itself.

What happens to fluids in a convection current?

Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it.

When the heat source is applied to fluid convection currents in the fluid will?

Answer: The heat energy can be transferred by the process of convection by the difference occurring in temperature between the two parts of the fluid. Due to this temperature difference, the hot fluids tend to rise, whereas cold fluids tend to sink.

How does convection remove heat?

Convection is the process of losing heat through the movement of air or water molecules across the skin. The use of a fan to cool off the body is one example of convection. The amount of heat loss from convection is dependent upon the airflow or in aquatic exercise, the water flow over the skin.

What happens during convection?

Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated. As a result, the particles take up more volume.

How does convection transfer heat?

Convective heat transfer is the transfer of heat between two bodies by currents of moving gas or fluid. In free convection, air or water moves away from the heated body as the warm air or water rises and is replaced by a cooler parcel of air or water.

How does convection contribute to the distribution of heat and moisture across Earth?

How does convection contribute to the distribution of heat and moisture across Earth? a moderate climate regulated by the ocean. carries hot air to the poles, where it cools and sinks, flowing back toward the equator.

What is a convection process?

convection, process by which heat is transferred by movement of a heated fluid such as air or water. Forced convection involves the transport of fluid by methods other than that resulting from variation of density with temperature. Movement of air by a fan or of water by a pump are examples of forced convection.

How does convection of heat work?

Convection works by areas of a liquid or gas heating or cooling greater than their surroundings, causing differences in temperature. These temperature differences then cause the areas to move as the hotter, less dense areas rise, and the cooler, more dense areas sink.
