Yes, it is correct.
Air is displace by water because water is much denser than air and therefor is much harder to compress.
It is easier to walk through air than through water because air is less dense than water, resulting in less resistance and making movement easier. In water, the increased density creates more drag, making it harder to move through. Additionally, water has a higher viscosity compared to air, further increasing resistance.
Air has larger spaces between the molecules as compared to those in water molecules so air compresses to a greater extent than water.
it shows that there is space between the model and iron is big and it attracts
The big reason is because air is air, and water is water. The second reason is because air is compressible, while water cannot be compressed. What that means is that if you compress air to twice the pressure, it will be one-half the volume. If you compress water to be twice the pressure, the volume won't change.
This is because condensation takes place after the compressor has compress the air in it.
It Is Easier To Clap Your Hands In Air Then In Water Because There Is Alot Of Space Between The Particles. Very Less Particles In The Given Space And Farapart That's Why It Is Easier
The buoyant force is greater on the rock in water.
They pump air into the chamber and compress it. Compressed air drives out the water. You must have room for air.
cause its easier for sound waves to travel through air than through liquid
You can try, but it wont work so well for you or the tank. Water doesn't compress easily. Things with air in them compress easily. Water does not have air. But if you try anyway, tell us how it goes.
The concentration of oxygen in the air is much much higher than in the water. This make obtaining oxygen much easier and strenuous activity (to a level higher than that is water) possible.
