As warm air rises, it leaves a 'void' which is filled by colder air being drawn in from the surrounding area. We feel this movement as wind.
It's density decreases, so will rise (or float) above surrounding cooler air.
Warm air rises....and when it rises it becomes cooler. ...If the pressure of surrounding air is reduced then the rising air parcel will expand. The molecules are doing work as they expand . This will affect the parcel's temperature.
Warm moist air rises because it is less dense than the surrounding cool air. As the warm air rises, it expands and cools, leading to condensation and the formation of clouds and precipitation. This process is known as convection.
There is no void because the reduced pressure brings in iar from surrounding areas.
Hot air rises because its molecules are less dense than the surrounding cooler air, creating buoyancy forces that cause it to move upwards. Conversely, cooler air sinks because it is denser than the surrounding warm air.
It all has to do with the gas law PV=nRT. When the Temperature "T" increases, the volume of the gas increases which inflates the balloon. It rises because this now warm gas rises through the cooler surrounding air. Warm air rises, cool air sinks
No. Convection occurs when warm air rises and cool air sinks. It is not limited to air, either, but can occur in virtually any liquid or gas.
