warm air is less dense than cold air due to the fact that the molecules in warm air have more energy and thus move farther apart from each other. This results in less mass per unit volume of warm air compared to cold air.
warm air and cold air gets together and make fog
No, hot air does not weigh more than cold air. In general, air at different temperatures still has the same mass per unit volume, or density. The weight of a given volume of air depends more on its mass and not on its temperature.
Cold air masses are denser and heavier than warm air masses. This is because cold air is more compact and contains more molecules per unit of volume, leading to higher air pressure compared to warm air masses.
No, warm air and cold air exert different pressures due to their different densities, but the weight of a volume of air is determined by its mass. Therefore, a mass of warm air does not weigh more than a mass of cold air, assuming the volumes are the same.
yes 1 mole hot air have more volume then cold air
Becasue the air gets cold!
when air is cooled it sucks
cold
'Cold' air will have less volume so the density is greater.
I hate questions like this one. Do you know why? Because I fear that the TEACHERS asking the question of their students are either IGNORANT of the subject matter they are supposed to be teaching or are asking a TRICK question of their students, which is almost always intellectually dishonest. Hopefully, it's just a poorly worded question by the poster of the question. Okay, I'll shut up and answer the question. A quantity of cold air can occupy a greater volume of hot air -- if there is more cold air than hot air!!!! If you've got two liters of cold air, that's a greater volume than one liter of hot air!!!!!! But what if you've got 0.1 kilogram of hot air and 0.1 kilogram of cold air? You've got the same amount of matter, right? They have the same mass: 0.1 kg. Will the hot and cold air occupy the same volume? NO!!! The hot air is less dense, which means it occupies MORE volume per unit mass than the cold air. So, if you have equal masses of hot and cold air, the hot air will have greater volume.
an air conditioner because it warms up to make cold air
As air (unconfined), is heated its volume increases, and its density decreases. That makes it lighter (per volume) than it was. Warm air will rise above colder air, and in essence, float on top of the colder air.
It does not so there can be no answer to your question.
what is does is it gets smaller in volume and then when you take it back out it will go back to it's regular volume ask more questions at answer.com
the air gets cold
When the cold front comes, the air mass gets lighter and thinner.
