hi Robert
Density
cold air sinks, warm air rises, and warm air can hold more water vapor than cold air can.
Yes, cold air masses are denser than warm air masses. The reason for this is because heat excites atoms so they take up more volume in space. Meaning they take up more volume of heat which leaves little warmth left and a lot of cold left. The warmth is thinner and vice versa, the cold is denser.
No it's just less dense. For the same volume of air, warm air is lighter.
No, cold air displaces warm air from the bottom because it's denser.

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.
yeah cold water is denser than room temperature (warm) water.
There are more atoms in cold air than warm.
Yes. Cold air is denser than warm air and thus the troposphere is denser in the winter than in the summer.
Cold air is denser than warm air. Which allows it to slide under that warm air and displace it.
COLD
The cold air is denser, because the cold atoms are thicker, denser, and have more mass. Warm atoms are less dense and move more, therefore creating heat.
When cold air moves into an area, we have high atmospheric pressure; the cold air is denser than the warm air. Love, me :)
Because cold air is denser than warm air.
Warm water is little bit hotter than cold water. The temperature of warm water is higher than that of cold water
