What else can I help you with?
A circular flow of warmer fluid and cooler fluid is called a?
A convection current, however, this can also occur with gases.
What do you need for convection to occur?
Convection occurs when there is a difference in temperature that causes a fluid (liquid or gas) to move. This movement is driven by the warmer, less dense fluid rising and the cooler, denser fluid sinking. The presence of gravity is also essential for convection to occur.
Explain why conduction and convection cannot take place in an airless vacuum like in outer space?
Conduction and convection require the presence of a medium (such as air or water) for the transfer of heat. In a vacuum, there is no medium to transfer heat, so conduction and convection cannot occur. Heat in a vacuum can only be transferred through radiation.
Why can't conduction and convection occur in space like radiation?
Conduction and convection require a medium to transfer heat, but space is a vacuum so there is no medium for these processes to occur. Radiation, on the other hand, can occur in the vacuum of space because it does not need a medium to transfer heat energy.
Can heat travel by convection through a vacuum?
No. Convection requires a carrier to convey the heat. Vacuum says there is nothing to do the conveying. Radiation does not need a convector, so heat can travel by radiation through a vacuum, like the radiation from the sun.
A circular flow of warmer fluid and cooler fluid is called a?
A convection current, however, this can also occur with gases.
Does convection occur in the core of a star?
No, Convection does not occur in the Core. For example, in the Sun, the convection occurs only after the Radiation zone. In the radiation zone the energy is transported by radiation (ie, by photons). At about 0.8 solar radius the density and temperature are not enough to transport the energy by radiation, so convection sets in.
What is more likely to occur in the water thermal energy transfer by conduction or convection?
Convection
What two states of matter can occur in convection?
Convection currents are in the liquid and gas states.
In which layer of earth does convection occur?
mantle
What types of matter does convection occur?
Convection occurs mainly in the gaseous state, where heat is transferred through currents in air. Convection can also occur in liquids, however it is generally identified with gases.gas and liquid
What 2 types of materials will convection most likely occur?
Convection is most likely to occur in fluids, such as liquids or gases, due to the movement of their particles. Additionally, convection can also occur in certain solids that are capable of flowing, such as molten lava or heated metals.
Where can a divergent boundary occur?
They occur when the convection currents are less dense and rise.
How does convection occur in convection chamber?
When smoke goes up through a tube to a container and into fire.
Why do convection currents not occur in some components of the structure of the earth?
Convection currents can occur in either a gas or liquid medium but not in a solid medium (so you can have them in air, and you can have them in magma, but you can't have them in solid rock) and they only occur when there is a temperature difference, so that hotter, less dense material will rise, and colder, denser material will sink.
Which layer of the earth do convection currents occur in?
Convection currents occur in the mantle, which is the middle layer of the Earth. The heat generated from the core causes the molten rock in the mantle to move in a circular pattern, creating convection currents.
What are the layers in the earth that convection currents occur?
uh me
