What does air do when it is heated in convection?
When air is heated in convection, it becomes less dense and rises. As it rises, it displaces cooler air, which then becomes heated and rises as well. This creates a continuous cycle of warm air rising and cool air sinking, which is known as convection.
Why doesnt convection occur when a beaker is heated at the top?
Convection occurs when heated fluid rises and cooler fluid sinks, creating a continuous circulation. If a beaker is heated at the top, the heated fluid near the top would rise but due to cooler fluid at the bottom, the circulation does not sustain itself, thus preventing convection from occurring.
What is the transfer of energy by the motion of heated particles in a gas or liquid?
This transfer of heat is called convection.
Can you use convection in a sentence?
Convection currents in the Earth's mantle drive the movement of tectonic plates, resulting in earthquakes and volcanic activity.
Does a lava lamp show convection when heated?
Yes, a lava lamp demonstrates convection when heated. The heat from the light bulb at the base of the lamp warms the liquid wax, causing it to rise to the top of the lamp. As the wax cools, it descends back down, creating a continuous cycle of convection.
Is the land heated by convection?
I think the land is heated by radiation
How does convection affect a stir fry?
Food is heated by conduction and convection.
Heat transfer by the movement of a heated fluid is called?
It is called Convection.
When the heated part of the mantle rises through the cooler parts this an example of?
Convection
How are convection and radiation?
They can be heated by 2 objects
When does convection take place?
convection takas place wen iron piece is heated
What does air do when it is heated in convection?
When air is heated in convection, it becomes less dense and rises. As it rises, it displaces cooler air, which then becomes heated and rises as well. This creates a continuous cycle of warm air rising and cool air sinking, which is known as convection.
Why a spoon is getting heated over a fire?
A spoon over a fire would would be heated from convection, because convection is when hot air rises and cold air falls which is known as a convection current.
How is air heated near the earths surfaces?
It's heated through the convection currents.
Why doesnt convection occur when a beaker is heated at the top?
Convection occurs when heated fluid rises and cooler fluid sinks, creating a continuous circulation. If a beaker is heated at the top, the heated fluid near the top would rise but due to cooler fluid at the bottom, the circulation does not sustain itself, thus preventing convection from occurring.
Find the mean for convection?
movement of air (HEATED)
Why does convection happens?
convection happens because fluids become less dense and expand and riseas they are heated.
