Temperature normally falls as you go up in the lower atmosphere, but there are many regions where it falls as you go up then rises for a while before falling more. Regions of the atmosphere where the temperature rises as you go up are called "inversions." Where I live, near San Diego, these inversions are very common and can be quite spectacular--some days the temperature may go up 20 degrees Fahrenheit or more when going from sea level to 2000 feet. So I guess the answer is that it can either get warmer or colder, depending on where you are and how high you go

Hot air does not rise because it is hot. Air rises because it is les dense than the air above it.

The densest air is at ground level and the atmosphere gets less dense as you rise through it. This means that warm dense air can be overlain by cooler less dense air. This is how the temperature falls as you get higher. The warm air near the ground will only rise when it becomes less dense than the air above it. If it remains denser than than the air above, it won't rise even though it is warmer.

The air inside a hot air balloon has been heated, it expands, filling the envelope and forcing some air out. This makes the air inside the envelope less dense than the surrounding air so it rises.

Warm air is less dense (lighter) than cool air, therefore it does rise. As the warm air rises, it cools. Think of it this way, the hot air balloon initially rises when you heat the air inside of it, the balloon will start to descend when the temperature of the air inside the balloon cools, therefore you have to keep heating the air inside the balloon if you don't want to crash. In other words, the air is cooler up there.

As you rise in the atmosphere, the air temperature generally drops. This is because there is a decrease in the air pressure as you rise, and a direct correlation exists between temperature and pressure. (the ideal gas law states that as pressure decreases, temperature decreases)

So yes - a parcel of hot air will rise (like that in a balloon), but the ambient temperature at altitude will usually be cooler than the air at the surface.

No, it would be cooler the higher you go up, that is where the freezing level comes in, when you watch the weather in your local area, some weather persons put up current conditions for your area, some include the freezing level, that is where the air is 32 degrees. This can vary from place to place, depending on what kind of weather you are getting at any particular time. So the higher you go, the colder it gets.

heat rises for a short distance and then turns into cold air
thats y ur upstares is warmer than ur downstars but its cold enough 4 the clouds to stay parcially frozen

I'm pretty sure it's cooler, heat does rise but the atmosphere isn't warm it's really quite cold

Actually, the higher you go the colder it gets.
