Density is the amount of mass per unit of space/volume.
For example, water has a density of around 1 kg/liter because 1 liter of water has a mass of 1 kg.
Something is less dense if the mass per volume is lower and more if it is higher.
Oil floats on water because it is heavier than the same volume of water (less dense), but a stone will drop to the bottom because it has a much higher density than its volume in water (denser).

Do winds blow toward less dense or denser areas?
Winds generally blow from areas of high pressure (denser air) to areas of low pressure (less dense air). This movement of air is due to the difference in air pressure between the two areas.
What does less dense and denser medium mean?
A less dense medium refers to a substance that has fewer particles or less mass per unit volume compared to another medium. Conversely, a denser medium has more particles or more mass per unit volume. Light travels faster in a less dense medium and slower in a denser medium.
Why do you think the denser plate subducts in a collision?
The colder, denser plate sinks beneath the less dense plate during subduction due to gravity. The older plate has had more time to cool and become denser, while the less dense plate is usually younger and has not had as much time to cool. This density contrast is a major driving force for subduction.
Is bromine gas denser or less dense than air?
Bromine gas is denser than air. At room temperature and pressure, bromine gas is about 7 times denser than air.
Is Warm air is less dense than cold air?
Yes, warm air is less dense than cold air because as air is heated, the molecules gain energy and move farther apart, resulting in lower density. Conversely, cold air is denser because the molecules are closer together due to lower energy levels.
Does more dense mean sink or float?
Typically, denser objects sink while less dense objects float. This is because denser objects have more mass per unit volume, causing them to displace less water than less dense objects, resulting in sinking.
Does polar water diluted by meltings ice become more or less dense?
less denser than
When a wave passes from a less dense medium to a denser one most of the wave energy is?
When a wave passes from a less dense to a denser medium, most of the wave energy is reflected back into the less dense medium.
Is natural gas is less dense than oil?
Of course less denser, because a gas is always less denser than liquid.
When a passes from a less dense medium to a denser one most of the wave energy is?
When a wave passes from a less dense medium to a denser one, most of the wave energy is answer is reflected FALSE
When plates collide the denser plate will ride over the less denser plate?
No, the denser plate sinks under the less dense plate in a process called subduction.
What is the sinking of denser water and rising of less dense water called?
less mater
When a wave travels from a denser medium to a less dense medium what happens to its frequency?
The frequency of the wave remains the same when it travels from a denser to a less dense medium. However, the wave will change its speed and wavelength.
Does polar water diluted by melting become more or less dense?
less denser than
Is carbon dioxide dense or more dense than air?
Carbon Dioxide is less denser than air.
Is oil denser then water?
No. It is less dense. That's why it floats above water.
Is alchohol denser than rubbing alchohol?
Pure ethanol is less dense.
