Hot air. Because it always rises above cold
Warm air. The humidity present in warm air makes it heavier.
Neither: One kilogram (weight) of air (or anything else for that matter) weighs one kilogram.
Warm air is less dense than cold air. (the density is mass per volume, mass is "weight")
cold because cold air drops and hot air rises
Hot air is lighter.
the cold air is denser
Strength is not a property of heat

Cold air
hot air
Hot air is lighter while cold air is heavier. This results in warm or hot air rising and cool or cold air falls.
Hot air hasLess atmospheric pressure, in other words the air is thinner. ... Cold air is heavier than hot air *at the same pressure*
You have forgotten one vital fact, cold air is heavier than hot air------At the same atmospheric pressure!!. That means that the cold air on Mt Everest is lighter than than the warm air 29000 ft below in the Ganges Delta.
Heat itself is a form of energy. This gives the air molecules more kinetic energy. Thus, with more kinetic energy, the air molecules move a lot more. Adversely, in cold air, there is less energy, thus the air molecules move less slowly. This is what gives hot air more volume than cold air. (Yeah I know I used more commas than I should've.)
this is because cold air is denser (when things lose energy or heat, they shrink), and heavier than the air in your house. when you oppen the door, the ouside air will rush in under the hot air in your house and the hot air will try to rise up and ouside.
Hot air rises, so is lighter than cold air.
cold air is heavier than hot air so the cold air gos to the hot air where theirs less pressure
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
Hot air is lighter while cold air is heavier. This results in warm or hot air rising and cool or cold air falls.
no cold air is heavier because it sinks and hot air rises
Gas is heavier than oxygen. Cold air is heavir than hot air
Cold air is heavier
Hot is the heavier molecule.

No. The hot air rises because it is less dense and therefore lighter. The cold air takes it's place as it is heavier. This causes wind.

during the the process of convection the hot air is lighter so the hot air rises up and the cold air is heavier so air conditioners cool down that hot air which has rose up
