In the convection current of a pan of soup the cooler denser fluid does what?
The denser fluid sinks to the bottom
What direction do convection currents move?
Warmer material in a convection current rises upwards.
The transfer of heat by the movement of a fluid?
convection
Heat is transferred by the movement of currents within a fluid by a process called what?
convection
How of these combines with changes in a fluid's density and the force of gravity to set convection currents in motion?
heating and cooling of a fluid
What activates a convection current starting a flow of fluid?
What activates a convection current, starting the flow of a fluid? A. cold temperatures at the north pole B. heated liquids at the earth's surface C. iron-rich rocks in the mantle D. temperature differences in the mantle
A circular flow of warmer fluid and cooler fluid is called a?
A convection current, however, this can also occur with gases.
A convection current transfers heat or air within a fluid?
a convection current transfers heat within a fluid.
How do you use convection current In a sentences?
Convection current is a stream of fluid propelled by thermal convection. Convection is mostly around gas and liquid
What is a current caused by the rising of heated fluid and sinking of cooled fluid called?
The current is called a convection current.
A circular flow of warmer fluid and colder fluid is called?
convection current
In a convection current the cold material will?
... move to the bottom of the fluid
In the convection current of a pan of soup the cooler denser fluid does what?
The denser fluid sinks to the bottom
What is the continuous flow that occurs in a heated fluid because of differences of temperature and density?
convection current
What is aconvection current?
A convection current is a natural flow or circulation of fluid due to a variation in its density due to temperature differences. As a fluid's temperature increases, its density reduces, and the fluid rises to be replaced by fluid at a lower temperature. Convection, together with conduction and radiation, is a method of heat transfer.
What form of energy leads to convection currents?
the form of energy would be heat. convection currents are caused by uneven heating of air or fluid. The warmer fluid is more boyant than the cooler fluid, so it floats to the top, and creates a "convection current"
What is the difference between current and convectional current?
Convection is the mode of heat transfer, referring to the transfer of heat energy due to bulk motion of a fluid."Convection current" is the name of that bulk motion of the fluid, the transfer of MASS. I prefer to call it buoyantly driven flow. It doesn't flow due to convection, convection is due to if flowing. It flows due to buoyancy in the case of free convection.Peyton
