Warm air is less dense then cold air.
But moist air is actually less dense than dry air because water vapor has a lower molecular weight than the oxygen and nitrogen that make up most of the atmosphere.
Cold salty water will be the most dense.
Cold salty water will be the most dense.
cold ocean water is more dense than warm water
In hot air the molecules move faster and exert more force when they collide. As a result there is more space in between the molecules on average.
Cooler material is more dense and hotter material is less. This means that plates become more dense as they cool.
Cold air is more dense than warm air.
Water is more dense the colder it becomes. It is also more dense the saltier it becomes.
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
Cold salty water will be the most dense.
Cold salty water will be the most dense.
Cold salty water will be the most dense.
Water is at its greatest density at 4 oC.
Yes, because the higher the temperature, the faster and more spread out the molecules, therefore making hot water less dense than cold water.
Air becomes more or less dense relative to its temperature. Cold air is denser than warm. Since the equatorial region is tropical, the air will be warmer and less dense.
Warm water is less dense than cold water, so it sits on top of the cold water. This is because warm water molecules are more spread out and have less mass per unit volume compared to cold water molecules, causing warm water to be less dense and float on top of the denser cold water.
cold ocean waer has more dense than warm water.
