What is unique about the materials convection takes place in?
Convection occurs in fluids such as liquids and gases, unlike conduction, which occurs in solids. During convection, the heated particles in the fluid become less dense and rise, while cooler particles sink, creating a circular motion that transfers heat.
Are heat vents examples of forced or natural convection?
Heat vents are an example of forced convection. Forced convection occurs when a fluid motion is caused by an external source such as a fan or pump, as opposed to natural convection, which occurs due to density differences in the fluid. In the case of heat vents, the air is circulated by a fan to distribute the warm air throughout a room.
What is the Difference in normal convection and forced convection?
Normal convection occurs naturally due to temperature differences, while forced convection is induced by external means such as fans or pumps. Forced convection typically has higher heat transfer rates compared to natural convection due to the enhanced fluid motion generated by the external force.
The layer of the earth where mantle convection occurs and on which the earth's crust rests is the?
The layer of the Earth where mantle convection occurs and on which the Earth's crust rests is the asthenosphere. This semi-fluid layer is located beneath the rigid lithosphere and plays a crucial role in tectonic plate movement. The convection currents within the asthenosphere facilitate the shifting of the tectonic plates that make up the Earth's crust.
Do convection currents happen when cool air rises?
No. Convection occurs when warm air rises and cool air sinks. It is not limited to air, either, but can occur in virtually any liquid or gas.
Why is convection?
convection occurs in fluids such as water and air
What occurs in mercury of a thermometer convection or conduction?
convection
Why is this convection?
convection occurs in fluids such as water and air
What does convection cell mean?
It refers to a region in which convection occurs.
How do you use convection in a sentence?
When convection occurs in the air, winds are formed.
What is the difference between conduction and convection a 5th grade answer please?
Conduction occurs in solids and liquids but not gases. Convection occurs in gases and liquids.
What does convection occurs in?
Convection only occurs in fluids. Fluids are gases or liquids.
What usually occurs in gases and liquids?
Convection
Why mantle convection occurs?
because your mom
Convection always occurs in what two forms?
Convection typically occurs in two forms: natural convection, driven by buoyancy forces due to temperature differences, and forced convection, driven by external factors like fans or pumps. Natural convection occurs in fluids (liquids and gases) due to density variations caused by temperature gradients, while forced convection involves the use of mechanical devices to circulate the fluid.
How convection occurs in a convection chamber?
When smoke goes up through a tube to a container and into fire.
Why does convection occurs in the athenosphere?
heat from the outer core and the mantle when it drifts up to the asthenosphere it causes convection.
