cold
Cool air, it is more dense.
The density of air is greater at lower temperatures and higher pressures. This is because the molecules are closer together in a given volume, leading to higher density. Cool, dense air sinks while warm, less dense air rises.
Yes, the cool air is lighter than the warm air and that is why Ac's are at the top or high level of the room so in this way when the AC gives out cool air it travels down and the warm air travels upwards and the whole room gets cool quickly.
If they are both under the same pressure and are the same in volume, then, yes, warm air has fewer molecules
Cool air has more pressure because it's particles are condenced and warm air has less air pressure because the particles in it are more spread out.
Because warm air is less dense then cool air.
Warm air is typically found above cool air due to the process of convection, where warm air rises and cool air sinks. This is why the upper atmosphere is warmer than the lower atmosphere in most cases.

A warm air is less dense than cool air (Option A). When air is heated, the air molecules become more energetic and spread out, decreasing its density. Conversely, cool air has denser molecules as they move slower and are more tightly packed together.
Cool air typically follows warm air. Warm air rises and creates an area of low pressure, which is then filled by cooler air moving in to replace it. This movement of air is known as convection.
The cold air pushes under the warm air.
When a warm air mass meets a cool air mass, the warm air mass rises because it is less dense than the cool air mass. This rising warm air can lead to the formation of clouds and potentially precipitation as the warm air cools and condenses. This process is known as frontal uplift.
