No, farther apart.
Hot air particles have more energy and move more quickly compared to cold air particles, which have less energy and move more slowly. This results in hot air being less dense and rising, while cold air is denser and sinks.
No, hot air is actually lighter than cold air. This is because the molecules in hot air move faster and spread out, resulting in lower density compared to cold air where the molecules are closer together and more tightly packed.
Cold air. At the same pressure, the VOLUME of a gas will be proportional to the absolute temperature - that is, to temperature expressed in Kelvin. Density is inversely proportional to volume.
The difference lies in the speed of particles, not in the composition or structure of the individual particles themselves. Temperature measures the average speed of particles, so the particles which compose hot air are going to be moving faster than the cold air particles. Because of this, the two take on new properties - hot air will expand more rapidly and rise, while cold air will sink.

Hot.
When air is heated, more kenitic energy is transfered to the airs particles. The particles then begin to move and vibrate more, and expand outward. This produces hot air, which rises because it has a lower density (more spread out particles) then the cooler air that surrounds it. Thus, it rises.
The inside particles of a hot air balloon are air molecules that are heated by the burner to make the balloon rise. The outside particles are also air molecules that create the lift force when the inside air is hotter than the outside air.

It becomes hot polluted air.
A liquid have random particles but they are still all joined together.

No, hot air is less dense than cold air. When air is heated, its molecules gain energy and move faster, causing them to spread out and decrease in density. Cold air, on the other hand, has slower-moving molecules that are packed closer together, making it denser.
