Wind represents both forced convection and natural convection heat transfer. Forced convection is when the movement of a fluid is driven by an external force (such as wind blowing over a surface), while natural convection is when heat is transferred through a fluid due to density differences caused by temperature variations.
No, wind is mainly caused by the movement of air in response to differences in air pressure. Conduction is the transfer of heat through solids or between objects in direct contact, not a direct cause of wind.
Hot air rising from a heater, water boiling in a pot, and wind blowing over a surface are all examples of heat transfer by convection.
By both way. Conduction is the basic of heat transfer, the energy (heat) is transfer from molecule to molecule from different in temperature gradient. Concept of convection is when there is motion of molecule come to concern like wind blow and take away the heat rapidly. Convection heat transfer can only occur in fluid state e.g. liquid and gas. In solid, only conduction heat transfer taken place.
Example: TV. Electricity- Heat, light, sound. Useful energy transfers would be electricity- light, sound because that's what your TV actually needs, but electricity- heat would be wasted energy or a non-useful energy transfer because your TV does not need to produce heat, unless of course you can't afford central heating, but then isn't heating more important than a TV???? Summary: Useful energy transfer: The purpose of the object is fufilled by this transfer. Non-useful energy transfer: The purpose of the object is not fufilled by this transfer, and in effect, this transfer is a "side effect" of the useful energy transfer. These transfers waste energy.
On a windy day, the rate of heat transfer through a pane of glass is greater because the wind carries heat away more rapidly due to convective heat transfer. The moving air next to the glass helps to remove the heat from the glass surface more effectively than on a calm day, leading to faster cooling.
heat transfer through convection.
through wind and circulating air.
Convection.
convection
Heat transfer determines weather. The wind blows around to settle weather.
Wind and water. Air currents (wind) carry heat poleward. This is mainly heat transfer by convection. Water currents carry heat poleward. This is heat transfer by convection and conduction.
i dont know but juan is a idiot

an energy transfer, with heat energy moving away from the equator
Hot air rising from a heater, water boiling in a pot, and wind blowing over a surface are all examples of heat transfer by convection.
convection causes the heat transfer.
Our planet is warmed by conduction (heat from the mantle below), convection (tropical heat is transferred to the poles by wind and currents) and radiation (primarily the warmth of the sun, though there's also radioactive decay occurring in our planet's core).
