Hot air is lighter while cold air is heavier. This results in warm or hot air rising and cool or cold air falls.
Thermals typically rise on the sunny side of a hill, where the ground has absorbed more heat and can then heat the air above it. This warmer air will rise due to its lower density compared to the surrounding air, creating lift for gliders and birds.
OK first of all I know you guys have got this question from K12.But anyway here is the answer:Sometimes warm air masses can get caught between 2 cold fronts which can for
Fronts typically form in cyclones, where warm and cold air masses converge. In anticyclones, air descends and diverges, leading to stable conditions, which hinder the development of fronts. Anticyclones are associated with fair weather and clear skies.

(Im not sure but i think i got it I've been looking through my text book) Air is a fluid made of gas so objects can float or rise because of the buoyant force produced by air pressure.
Old boat got sink
because you got to light it....commen mistake
Cold air is more dense than warm air, and we know that more dense things sink and less dense things float. It does not matter how the co2 got hot it loses it heat to what ever is around it. Heat goes up and the hotter it gets the fast the heat rises and that is why global warming is a lie.
Coffee grounds are denser than water, so they sink when added to cold water. This is due to gravity pulling the denser coffee grounds downward into the water until they reach the bottom of the container.
it did not sink he got his head cut dff
Obviously it is broken.
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.
Most likely the warm-cold air separator got stuck or the servo (or rod if you have manual air system) mechanism failed.
NO, it got taken by aliens
When it got a hole in the bottom.When it got flooded with water.:D
i had caught cold
The older an egg, the more air has got into it so to test how fresh and safe your egg is to eat, put it in a beaker/jug of water and it should sink completely to the bottom.
