c)wood
d)an aluminium plate
Answers
Answer:
d)an aluminium plate
Explanation:
Because hot liquids and gases are less dense than cold ones, they ascend into the cold zones. The warmer places receive the denser cold liquid or gas. Convection currents that move heat from one location to another are created in this manner.
Currents in Convection
A convection current is a process that includes the transfer of energy from one location to another. It is also known as heat transfer through convection. What causes you to feel hotter when you sit near or place your hands over a campfire? Or, why does boiling water in a saucepan cause the liquid to flow quickly? Convection Currents cause these events to occur.
A fluid or gas particle will often be transported from one location to another by convection currents. These are brought about by variations in the densities and temperatures of a particular gas or fluid. One of the two types of heat transport, the other being radiation and conduction, is convection. Convection only takes place in fluids, such as gases and liquids. Because molecules inside liquids and gases are free to move, this occurs.
The difference in temperature between the two fluid components allows the heat energy to be transported through convection. Hot fluids tend to ascend, whereas cold fluids tend to sink due to this temperature differential. A convection current is produced as a result inside the fluid.
Convection currents drive the movement of the mantle under the planet's surface. A highly hot substance found in the deepest region of the mantle, which rises, cools, and falls again, repeating the heating and rising process, is the major source of these currents.
Therefore, "a process of continual heating up of liquids or gases through the mechanism termed convection" is the definition of convection current.
