true
Colder air sinks downwards, as it is denser than warm air. It is denser/heavier than warm air because the molecules are more crowded than warm air.
cold fronts are heavier than warm fronts
a warm front
Yes, cold air does have a higher density than warm air. For example, if you turn on the fireplace, all of the warm air rises to the ceiling. On the floor, the air is cooler.
Cold air is heavier than warm air.
Cold air is heavier than warm air. Therefore you want the cooler near top so the cool air will flow down over the food etc.
False because warm air rises. The particles in cold air are moving more slowly and make cold air more dense than warm air.
cool air is heavier than war air.
Warm air is less dense than cooler air.
The density between cold and warm air is, cold air is heavier than warm air.
true
Cooler air is more dense than warmer air, that means that for a unit of volume cooler air will be heavier.
cold air is heavier than the warm air warm air has low water so it is hot and low heavy but cold air has a lot of water so it cold and heavy
Colder air sinks downwards, as it is denser than warm air. It is denser/heavier than warm air because the molecules are more crowded than warm air.
the warm air rises because of its Kinetic energy !
Cold air is heavier
