No, cold air does not always go up. In fact, cold air is denser than warm air, which causes it to sink rather than rise. This density difference is why cold air often settles at lower altitudes, while warm air rises. However, under certain conditions, such as during a weather front or with turbulence, cold air can be displaced upwards.
Warm air rises because it is less dense than cold air, creating convection currents. Cold air sinks because it is denser than warm air. This movement of air creates weather patterns and influences temperature gradients in the atmosphere.
Cold air is more dense than warm air. If flows beneath the warm air and forces it to rise.When air warms up, it expands a little, and so it becomes less dense. Density is the ratio of mass to volume. Within a fixed volume, there will be less mass (less air) in a sample of warmer air than there will be in a sample of cooler air. The less dense air floats above the cooler air. This is why hot air balloons will rise.
Hot.
At the poles, cold air sinks. Simple
In the process of heat transfer, hot air moves to cold air.
When using a ventilation system, hot air goes out while cold air comes in.
it is better ot launch a hot air balloon on a cold day than on a warm day because the air rises in the atmosphere therefore if you were to go for a cold day you would go very high but if you were to go a ride on a hot day the hot air balloon wont go as high as on the cold day .
Well the main reason why your car blows out cold then hot is because the air conditioner may not be working properly. You should go to the car shop and get it fixed.
Alligators are cold blooded. They dislike both high and low temperature extremes. They go into the water because the water will be cooler than the hot outside air on hot days, and warmer then the cold air on cold days. Water takes a length of time to 'catch-up' to the air temperature above it so it has a moderating effect for the alligator.

"Smoke", strictly speaking, consists of particles of ash carried on the hot air from burning. Since hot air is less dense than cold air, it rises as it is displaced by the heavier cold air.

Hot air rises in relation to its surrounding environment. This is because hot air is less dense than cold air, causing it to be buoyant and move upwards.

The gases produced during the process of burning are hot. Hot air is lighter than the cold air. So the flames go upwards.
the earths core is never hot it is always going to be hot the lower you go the hoter it gets.p.s. your welcome :) say thank you ;)
