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.
Cold salty water will be the most dense.
Cold salty water will be the most dense.
No, convection occurs when warm air, which is less dense, rises and cold air, which is denser, sinks. This process creates a cycle of air movement where warm air is replaced by cooler air, facilitating heat transfer. If cold air were less dense than warm air, it would not rise, disrupting the convection process.
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 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.
True... warm water is less dense than cold water.
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
When dense,cold air meets less dense,warmer air, the warm air is pushed up
When dense,cold air meets less dense,warmer air, the warm air is pushed up
Cold air is more dense than warm air.
Warm water tends to stay on top of cold water because it is less dense. When water is heated, the molecules move farther apart, making warm water less dense than cold water. This difference in density causes warm water to float on top of cold water.
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.
When dense,cold air meets less dense,warmer air, the warm air is pushed up
yes
it rises
Cold salty water will be the most dense.
