Cooler denser air is pulled down by gravity but is also pushed down by the rising hot air. This process is called convection.
The density of a cool gas is lower compared with the density of a hot gas; consequently the cooler gas is pulled down.
Yes, cooler and denser air is indeed subject to the force of gravity, which causes it to sink closer to the Earth's surface. This process is known as atmospheric subsidence, and it often occurs in areas where air is cooling and becoming denser, leading to high pressure systems.
Cooler particles are pulled down by gravity in the troposphere, which is the lowest layer of Earth's atmosphere where most weather phenomena occur. As air cools, it becomes denser and sinks due to gravity, creating convection currents that drive weather patterns.
Hot air rises because it is less dense than cooler air. As the hot air expands, it becomes less dense and is pushed up by the denser, cooler air surrounding it. This creates convection currents, with hot air rising and cooler air sinking.
Warm air is displaced by cooler denser air
Cooler air tends to sink and accumulate in low-lying areas such as valleys due to its higher density compared to warmer air. The lack of wind on calm nights allows the cooler air to settle in the valley and create temperature inversions, where the air near the ground is cooler than the air above.
Objects that are heavier than water will sink down, such as metal objects or rocks. Additionally, liquids and gases can sink down into a denser medium, like oil sinking down in water or hot air sinking down in cooler air.

become denser and move closer together, causing the balloon to shrink as the air inside cools down and contracts.
Hot air rises because it is less dense than cooler air. As hot air expands, it becomes lighter and more buoyant, causing it to move upwards towards cooler, denser air. This movement is known as convection.
When air cools, its density increases because cooler air is denser than warmer air. This results in a decrease in volume, as cooler air contracts. Additionally, the relative humidity can increase, as cooler air can hold less moisture, leading to the potential for condensation.
It is hot, and less dense than the air it displaces. It floats of the cooler, denser air.
