How are currents that form in heated air similar to currents that form in heated water?
Currents that form in heated air are similar to currents that form in warm water because heated air goes up and cold air goes down creating convection currents.
Why cant convection currents form if they are heated from the top?
The convection current can't form if heated at the top because then, the hot air would just keep getting hotter; no air moves around.
Why are there warm air currents over motorways?
Because of convection currents
Convection currents form when warm air rises and cold air sinks What causes the warm air to rise and the cold air to sink?
a difference in density
Convection currents form when warm air rises and cold air sinks. What causes the warm air to rise and the cold air to sink?
a deference in density
What should the air temperature be for the convection currents to form?
has to be cold
How are currents that form in heated air similar to currents that form in heated water?
Currents that form in heated air are similar to currents that form in warm water because heated air goes up and cold air goes down creating convection currents.
Which diagram correctly indicates why convection currents form in water why water is heated?
which diagram correctly indicates why convection currents form in water when water is heated
How do difference in air density cause convection currents?
It just happens because of the differenciation in the air density which allows the so called convection currents to occur/form. Complex I know but is the closest conclusion.
A radiator heats a room by heating the air which circulates in convection currents?
Yeah you are right convection currents are movement of the air
What form of energy leads to convection currents?
the form of energy would be heat. convection currents are caused by uneven heating of air or fluid. The warmer fluid is more boyant than the cooler fluid, so it floats to the top, and creates a "convection current"
How do glider use convection to stay flying?
Convection allows warmer air to rise because it is less dense than colder air. Because temperatures are greater near the ground (due to the ground's absorption of infrared radiation from the sun), the air at ground level tends to be warmer than the air at higher altitudes. Therefore, the air at ground level rises to form convection currents (currents of rising air), which, when impacting a glider's wings, generates lift, which allows them to remain in the air, or even rise to higher altitudes.
Can heat be transferred in the air?
Yes, in pockets of air, energy in the form of heat can be transferred by either convection currents, or by radiation.
Why cant convection currents form if they are heated from the top?
The convection current can't form if heated at the top because then, the hot air would just keep getting hotter; no air moves around.
Which process do air currents transfer heat energy throughout the room?
convection
Where does water vapor go when it enters the air?
Water vapor triggers convection currents that can form clouds.
Why are there warm air currents over motorways?
Because of convection currents
