Cold air is denser than warm air. The molecules are packed closer together. The amount of water vapor in the air also affects the density of the air. The more water vapor that is in the air, the less dense the air becomes.

Explanation:
When we compare cold air with hot air, we can observe that cold air is denser and heavier than hot air. This is because of the difference in the physical properties of both types of air.
Density:
Density is defined as the amount of mass present in a unit volume of a substance. In the case of air, the density is affected by temperature. When the air is heated, it expands and becomes less dense. Similarly, when the air is cooled, it contracts and becomes denser.
Temperature:
Temperature is the measure of the average kinetic energy of the particles in a substance. In the case of air, the molecules move faster when the air is hot, and slower when the air is cold. This means that the molecules in hot air are more spaced out and have more room to move than the molecules in cold air.
Pressure:
Pressure is defined as the force exerted by a substance per unit area. In the case of air, pressure is affected by density. When the air is denser, it exerts more pressure than when it is less dense.
Conclusion:
Therefore, we can conclude that cold air is denser and heavier than hot air because of the difference in their physical properties.
