Hot air is less dense than cold air. According to the ideal gas law, PV=nRT (where V=volume and T=temperature) Since all the other factors (P=pressure, n=mols of gas, R=gas constant) remain constant, as you increase temperature you increase volume. Since volume increases, and the mass stays the same, the hot air's density decreases. (Density=mass/volume) Less dense things rise above more dense things, such as alcohol rising above water.
Yes, both cold fronts and warm fronts can act as lifting mechanisms in the atmosphere. Cold fronts tend to lift warm, less dense air rapidly, creating instability and often causing strong thunderstorms. Warm fronts, on the other hand, gradually lift over cooler air, typically leading to more widespread and prolonged precipitation events.
Cold air is denser than warm air because the molecules in cold air are closer together, leading to higher density. Warm air, being less dense, rises above cold air as part of the process of convection. This difference in density is a key factor in determining atmospheric stability and weather patterns.
When cold air moves toward warm air, it pushes the warm air upward because cold air is denser and therefore heavier than warm air. This creates a lifting mechanism known as cold air advection, which can lead to the formation of clouds and precipitation.
No, a warm front forms when a warm air mass advances and overtakes a retreating cold air mass. As the warm air rises over the cold air, it cools and condenses, creating precipitation and leading to a gradual warm-up in temperature.
When dense cold air meets less dense warm air, the warm air is forced upward due to the difference in density. This can lead to the formation of clouds and precipitation as the warm air rises, cools, and condenses. This process is known as atmospheric convection.
When warm air moves into a region occupied by cold air, the warm air will rise above the cold air due to its lower density. This results in the cold air being displaced and pushed out of the region, a process known as warm air advection. This movement can lead to changes in temperature, pressure, and weather patterns in the region.
the warm air is pushed down because its lees dense than the cold air if cold air is more dense.

Warm air is lighter than cold air. So you'll always get warm air on top of cold air when they meet.
The warm air mass carries warm moist air. The cold front brings cold, dense air. Because this cold air is denser, as it ploughs through the warm moist air it forces it upwards. This warm moist air being pushed up at speed is what causes cumulonimbus clouds to form along the cold front, and hence thunderstorms.
