Miners don't use convection currents because underground mining operations involve working in confined spaces that lack proper ventilation for natural convection to occur. Additionally, convection currents are not reliable or controllable enough to ensure efficient mining operations through rock removal. Instead, miners rely on engineered ventilation systems to provide a safe and controlled environment for workers.
The thermal energy transfer that occurs by the motion of fluid in liquid or gas is known as convection. This process involves the transfer of heat by the movement of a fluid due to density differences created by temperature variations. Convection is a key mechanism for distributing heat in fluids.
Convection and conduction are not impossible, but they may be limited by certain conditions. For convection to occur, there must be a fluid medium like air or water that can transfer heat through movement. Conduction requires direct contact between two materials for heat transfer to take place. If these conditions are not met, convection and conduction may be less effective or impractical.
Plates move due to the process of plate tectonics, which is driven primarily by mantle convection. The heat generated from the Earth's core causes the mantle to circulate, creating currents that move the tectonic plates above it. This movement can result in various geological phenomena such as earthquakes and volcanic activity.
The current of electrons moving through resistors changes into heat due to the resistance encountered in the material. This process is known as Joule heating, where electrical energy is converted into thermal energy.
the process whereby heat moves from one body or substance to another by radiation, conduction, convection, or a combination of these methods. Heat transfer flows from a body with high energy (higher temperature) to lower energy (lower temperature).
i really dont know diz answer it is pretty hard for mhe to figure out
they look for gold!!! When they dont do that their with there wife!!
alot i dont know
dont know but they try and find diamonds
...just dont
i dont know i am trying to figure out too!
I dont believe its even a word. I'd say you mispelled it and meant to ask what's convection. I search'd for convection on wikipedia and i found this http://en.wikipedia.org/wiki/Convection Check it, you.
dont no
i dont now
