This process is repeated for conditions representative of real tests where the prescribed heat flux the velocity and the air temperature are transient.

. 5 What causes the global transfer of heat. 1 What Causes Global Convection Currents To Form. 2 What caused the global convection currents between the equator and the poles.

Tru e Correct Answer. Basically convection is heat transfer via fluid flow. Convection is heat transferred by movement of a fluid.

I DONT GET THIS QUESTIONConvection is a form of heat transfer best described as _____. Convection is a form of heat transfer best described as heat transferred through contact between atomsmolecules heat transferrred by the movement of a fluid which may include air water molten rock. Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids.

Circular movements of heated fluids that help spread the heat. Convection heat transfer is the process of transfer of heat energy between a surface and a fluid in motion. C The process in which energy is released by molecules breaking apart.

5 Bulk discount. Convection or convective heat transfer is the transfer of heat from one place to another due to the movement of fluid. The transfer takes place from the solid surface to the fluid and is commonly observed in heat exchangers.

Heat convection is often the primary mode of energy transfer in liquids and gases. Heat convection is the transfer of thermal energy by the physical movement of fluid liquid gas or plasma from one location to another. 6 What is the main source of heat that triggers convection currents.

For example an air conditioner cools a space by cooling the rooms inside air and removing hot air. Transfer of heat from one place to another due to the molecular movement of fluids such as air or liquid is known as convective heat transfer. Although often discussed as a distinct method of heat transfer convective heat transfer involves the combined processes of conduction heat diffusion and advection heat transfer by bulk fluid flow.

When air molecules move from one place to another they carry heat energy. Heat transferred through contact between atomsmolecules Response Feedback. T s is the surface temperature.

When you watch steam rise from a cup of hot chocolate or watch vegetables boiling in water or cooking in a steamer you are observing this effect. The dominant form of heat transfer in liquids and gasses is through convection and involves heat diffusion conduction and heat. B The process in which energy is emitted by one object transmitted through space and absorbed by another.

The equation to calculate the rate of convection is as follows. Heat transferred through space via electromagnetic radiation Looking for a Similar Assignment. D Transfer of heat by the actual movement of warmed matter.

A is the area of heat transfer. Heat transfer through convection occurs other through diffusion or advection or both. Question 5 3 out of 3 points Some incoming solar radiation gets reflected by the clouds and never reaches Earths surface.

Heat 4000 1600. The initial heat transfer between the object and the fluid takes place through conduction but the bulk heat transfer happens due to the motion of the fluid. Cooler soup at top sank down to bottom so now that is closest to the heat and rises up as it gets hot.

The term natural convection is used if this motion and mixing is caused by density variations resulting from temperature differences within the fluid. Convection is the process of heat transfer in which transfer of heat energy occurs by the mass movement of molecules of the fluids like gases and liquids. Convection and conduction only.

Example of convection current. Heat transferred through contact between atomsmolecules Correct Answer. Convection currents in the water cause warmer denser water to rise and transfer energy upward.

Question 45 3 out of 3 points Conduction is a form of heat transfer best described as _____________. Up to 10 cash back Using the framework described above the heat transfer coefficient and radiative heat flux are recovered. Which of the describes convection.

Q h c A T s T f Where Q is the heat transferred per unit time. 3 What are the three causes of convection currents. I DONT GET THIS QUESTIONConvection is a form of heat transfer best described as _____.

When the transfer of heat takes place from one part to another part of the substance or fluid due to the actual motion of the molecules it is called the convection mode of heat transfer. Convection is the process by which heat flows from the region of higher temperature to the region of lower temperature by the actual movement of the particles of matter. Convection currents move thermal energy from the stove to the pot and then from the pot to the water.

After the stove is turned off convection currents continue to transfer energy through the water for a period of time. Convection involves the transfer of heat by the motion and mixing of macroscopic portions of a fluid that is the flow of a fluid past a solid boundary. Cold soup in pot at bottom heats first and begin to rise to top.

H c is the coefficient of convective heat transfer. A Transfer of heat between two objects that are touching. In this method the rate of heat transfer depends mainly upon the difference in the fluid density at different temperature.

Since these points occur at low convective heat transfer it is best to assume. Heat transferred through contact between atomsmolecules. Convection occurs because fluid that is heated becomes less dense and as a result it rises.

Heat transferrred by the movement of a fluid which may include air water molten rock heat transferred by Sparky the Sun Devil. Convection is a form of heat transfer best described as _____. Each particle comes to take the heat becomes lighter and moves up.

Along with conduction and radiation convection is one of three basic methods of heat transfer. Helpful 0 Not Helpful 0 Add a Comment. 4 What causes a convection current in the air.

In liquids and gases heat travels by convection. The colder ones keep on moving down get heated and move up.
