| What is generally the best conductor: a solid, liquid or gas? | solid |
What is convection and where does it occur?
Convection is a transfer of heat related to the movement that occurs within a fluid due to the rising of hotter materials paired with the sinking of colder materials. This occurs because hotter materials have less density than colder ones.
How is conduction different from convection?
In conduction, heat transfer takes place between objects by direct contact. In convection, the heat transfer takes within the fluid. The heat transfer occurs through a heated solid object.
What state of matter does convection work best in?
Convection is the transfer of heat energy through the movement of fluid particles. Hence, convection cannot take place in solids, since the solid particles are not fluid. Thus, convection only takes place in liquids and gases.
In which states of matter can convection occur?
Answer. Convection is the transfer of heat energy through the movement of fluid particles. Thus, convection only takes place in liquids and gases.
Where does convection happen in every day life?
Convection occurs at the bottom of the oceans where the energy of the water meets the surface that is cold, and results in ocean currents. When a volcano is erupting it is because the force of gravity has attracted its hot fluids to the surface, the rest of the fluids descend.
Which layer of the Earth is the place where convection occurs?
Convection occurs in the mantle of the Earth. Convection currents are the movement of fluid as a result of differential heating or convection. In the case of the Earth, convection currents refer to the motion of molten rock in the mantle as radioactive decay heats up magma, causing it to rise and driving the global scale flow of magma.
What are some real life examples of convection?
Examples of Convection: 1. Heating Water on the Stove. When a pot of water is placed on a stove and the stove is turned on, the pan itself becomes increasingly hotter due to conduction; that’s where the metal of the pot is directly in contact with the heating element. But the water inside the pot is heated due to convection.
What are 5 facts about convection currents?
Vertical circulation within a fluid that results from density differences caused by temperature variations. In meteorology, the process in which air, having been warmed close to the ground, rises. Within the Earth, the radiogenic heat release results in convective motions causing tectonic plate movements.
