What else can I help you with?
If the mass of a fixed volume of air increases does the density become more or less dense?
If the mass of a fixed volume of air increases, the density of the air becomes more dense. Density is defined as mass divided by volume, so as the mass increases while the volume remains constant, the density increases.
Is the air inside of a balloon more dense or less dense than the air around it?
The air inside a balloon is less dense than the air around it. When the balloon is inflated, it contains less air molecules compared to the same volume of air outside the balloon, making it less dense.
What happens when there is less mass in a given volume air?
The air is less dense.
Does air with greater density contain more or less molecules than less dense air?
Yes, given the same volume of both.
Volume of warm air weighs less than an equal volume of cold air because?
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.
If the mass of a fixed volume of air increases it becomes less?
If the mass of a fixed volume of air increases, it becomes denser. This means that there are more air molecules present in that volume, making the air more compact and heavier.
If the mass of a fixed volume of air increasesit becomes less dense?
No, it does not.
What will less dense air do in a relation to more dense air?
if two fluids of different density meet the less dense one will rise over the more dense one.
Is cool air less dense?
No it is more dense than hot air
Statement correctly describes how the density and temperature of air are related?
Lower temperature air is more dense.
Is warm air less or more dense?
Warm air rises because it is less dense than cold air. Kinetic molecular theory tells us that warmer particles move faster than colder particles. (That's how we define a substance to have "heat".) You can imagine that faster particles are going to bump into each other more often, pushing other particles away. So, yes. Warmer = less dense = rising. In all things.
Is ammonia more dense or less dense than air?
Ammonia is less dense than air at room temperature and pressure. This is why ammonia gas rises in air.
