What air causes molecules to move slowly?
Extremely cold air.
What type of front forms from cold air move underneath warm air forcing the warm air to rise?
This is a cold front.
When a cold air mass meets a warm air mass and does not move its called a what?
Stationary front
Do air molecules move fast in hot weather or slow?
Air molecules move faster in hot weather and slower in cold weather.
When a cold air mass and a warm air mass meet and neither can move the other the result is a?
a tornado
Why does the cold air near a ice lolly move downwards?
Cold air, being more compacted in it's gaseous molecules, is heavier than warmer air, so it sinks.
Why does the cold air near ice lolly move downwards?
Cold air, being more compacted in it's gaseous molecules, is heavier than warmer air, so it sinks.
Why does a cloud of dry ice flow downwards?
It flows downwards because it is cold and cold air sinkse. The most important reason why it flows downwards is that dry ice is made of CO2 / carbon dioxide which = 1.5 times heavier than the air that we inhale.
Does hot air move into cold air or does cold air move into hot air?
Both. Since hot air is less dense than cold air, the hot air rises as the cold air falls (i.e. as the cold air displaces the hot air). If you were to dye hot air & then inject it into the center of a room, you would observe the dyed hot air rising. What you may not realize is that gravity draws the (invisible) surrounding dense cold air downwards as it displaces the (visible) less dense dyed hot air. === Previous Posters Answer: Hot air rises
How does air above a cold surface?
how does air above cold surface move
Does cold air move towards warm air?
Yes
Why do cold air particles move fast?
The statement is not correct; cold air particles move slowly because they lack the kinetic energy they need to move fast, which is heat.
What way do cold air molecules move?
In cold air, molecules move slower then they would move in warm air. One part of the KPM (kinetic particle model) states that temperature directly effects the movement of the particles, therefore causing the molecules of the warm air to move faster (because of more frequent collisions between the molecules).
Why does flames of a fire rise even though gravity pulls things downwards?
Because the warm particles/air from the fire are lighter than the cold air around it. The warm air, being lighter, rises, and the cold, heavy air sinks. Cold air is pulled into the bottom of the fire, warmed and continues the cycle.
What air causes molecules to move slowly?
Extremely cold air.
Why are air conditioners are usually placed at a higher level rather than at a lower level?
Heat rises, cold falls. Hot air will rise towards the ceiling, while cold air will travel towards the floor. Thus, it's beneficial to have the air conditioning at a higher level to allow the cold air flow downwards.
What type of front forms from cold air move underneath warm air forcing the warm air to rise?
This is a cold front.
