The escape of heat from a cooling mass is effected by conduction, or by convection, or by both.
"Yes, it makes its own ventilation; convection," Jacquemont said.
The convection on the contrary should be the smaller, the higher the frequency.
This was placed in the room and provided heat by conduction, convection, and radiation.
This mode of propagation may better be described as a convection of excitation.
But the ocean gathers its heat by convection from the earth.
The tube C is a connecting tube bent downwards so as to prevent the mixing of the solutions by convection currents.
It explains the law of convection, or heat distribution, over the surface of the globe.
This will be composed of a conduction and a convection current, the latter due to rising or falling air currents carrying ions.
Owing, also, to this law of convection, the constituents of the air are equalised.
convection con·vec·tion (kən-věk'shən)
Heat transfer in a gas or liquid by the circulation of currents from one region to another.
Fluid motion caused by an external force such as gravity.
Current in a fluid caused by uneven distribution of heat. For example, air on a part of the Earth's surface warmed by strong sunlight will be heated by contact with the ground and will expand and flow upward, creating a region of low pressure below it; cooler surrounding air will then flow in to this low pressure region. The air thus circulates by convection, creating winds. See Note at conduction.
The motion of warm material that rises, cools off, and sinks again, producing a continuous circulation of material and transfer of heat. Some examples of processes involving convection are boiling water, in which heat is transferred from the stove to the air; the circulation of the atmosphere of the Earth, transferring heat from the equator to the North Pole and South Pole; and plate tectonics, in which heat is transferred from the interior of the Earth to its surface.
