Cold air is denser than warm air, so it exerts a higher pressure. When cold air moves into an area, it can increase the air pressure in that location. Conversely, when warm air moves into an area, it can decrease the air pressure.
Cold air tends to sink and move downwards in a room, while warm air rises and moves upwards.

As warm dry air moves into an area, it typically indicates stable weather conditions will persist. In this situation, the barometer is likely to show high pressure, leading to clear skies and minimal chances of precipitation.
When a warm object touches a cold object, heat energy is transferred from the warmer object to the cooler object. This transfer of heat causes the warmer object to cool down and the cooler object to warm up until they reach thermal equilibrium.
I. The cold air mass is pushed underneath the warm air mass.

a cold front
When a warm front moves into a cold front, the warm air gradually rises over the denser cold air. This can lead to the formation of clouds and precipitation. The warm air displaces the cold air, leading to a gradual increase in temperature and humidity.
The warm air mass is forced up and over the cold air mass, resulting in the development of a cold front.
fog
The contact zone is called a cold front.
Warm water of course.
Cold
As a hurricane moves over cold water, it loses its main source of energy which is the warm ocean water. This causes the storm to weaken and eventually dissipate as it lacks the warm water needed to maintain its strength and intensity.
a warm front moves faster then a cold front because it is less dense
Warm air moves over cold air and replaces it.
