It's because colder air is much denser than hot air. The molecules in hot air are farther apart (expand - lighter), while the molecules in cold air are closer together (condense- heavier).
When air is heated, it expands because the gaseous particles gain kinetic energy. The formula density = mass/volume implies that the density of a substance is inversely proportional to its volume (provided that its mass is constant, which in turn means constant amount of that substance based on the number of moles). Therefore an increase in volume means a decrease in density.
Therefore, cold air has a higher density compared to hot air. This is why hot air balloons can rise up to the sky!
Any object that is heated becomes less dense and expands making a cc of it lighter, This is because the molecules that make it up become more exited and require more room as they are bumping into each other.
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
No, warm air is less dense than cold air because the molecules in warm air have more energy and are spread out more, resulting in lower density.
Warm air masses are less dense than cold air masses because warm air molecules have more energy and are more spread out, leading to lower pressure. Cold air masses are denser because cold air molecules are closer together and have less energy, resulting in higher pressure.
Warm air rises because it is less dense than cold air, due to the expansion of its molecules. Cold air sinks because it is more dense than warm air, as its molecules are more closely packed together. This movement creates convection currents as the warm air replaces the cold air.
Warm air is less dense than cold air because the molecules in warm air have more energy and are more spread out, resulting in lower density. Cold air is denser because the molecules are closer together and moving slower.
cold ocean water is more dense than warm water
Cold air is more dense than warm air.
Cold air is more dense than warm air.
Yes, it would.
Cold water is more dense.
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
cold ocean waer has more dense than warm water.
Cold Air is more dense than Warm Air.
the warm air is pushed down because its lees dense than the cold air if cold air is more dense.
Water is more dense the colder it becomes. It is also more dense the saltier it becomes.
No, warm air is less dense than cold air because the molecules in warm air have more energy and are spread out more, resulting in lower density.
Cold air is more dense than warm air and therefore heavier
