29 авг. 2015 г. · Hot air radiates only a little bit as a heat source, that is also known as cooling. Hot air rises because it has lower density than cold air.

29 июн. 2018 г. · That said, heat is just rapid vibration of atoms/particles. So it tends to rise up above slower moving atoms/particles. Space is very cold, ...

It's not the "heat" that is rising, it's the heated gases (air) that is rising. To understand this, let's say for example that we have a 1 square meter cube of ...

From the Ideal Gas Law, if you hold pressure constant, then an increase in temperature means a decrease in density. So if you have a blob of air that is warmer ...

27 сент. 2019 г. · Air is like a thick blanket on the earth keeping the warmth in. When you go up to high altitude there's a thinner blanket over you, so it's cooler.

13 июл. 2014 г. · Hot air only rises in the lower atmosphere because temperature decreases with height there. Imagine you have an extra warm parcel of atmosphere ...

I thought that because the temperature was warmer, that meant it would be a lower pressure, and thus the altimeter would indicate a higher altitude than the ...

27 дек. 2023 г. · If you heat up air in a sealed rigid container, then the density will not change because both the mass and volume of the gas are fixed.

11 сент. 2023 г. · No, that heavily depends on the amount of time. Basically, the Energy needed to heat it up needs to be less than the losses over the time. If ...

15 янв. 2024 г. · Since hot air rises, the heat you're feeling is due only to radiation, which transfers heat in all directions. Upvote 2. Downvote Reply ...
