It is easier to move through air than water because air is less dense than water. In other words, there is less matter per square inch in air than there is in water.
First of all, air is a gas, and water is a liquid. In the atomic structure of a gas, the atoms have much greater space to move around in as they are not bonded to each other in any way. In water, the atoms are closer together, and move together. This can be seen just by pouring water and sloshing it around in a glass - if you apply force in one direction, the water all moves in that direction. It takes a lot of force to get the same reaction out of gas.
Hence, the idea of "matter per square inch" - for the amount of liquid you would fit in an area, you could fit less gas in that area at the same ppi.
So, for this reason, it is easier to move against gas than liquid - where you're moving many particles of liquid out of the way, the gas is much more spread out and thus easier to move through.

What substance enters and leaves a plant cell through the process of osmosis?
Water enters and leaves a plant cell through the process of osmosis. When the concentration of water inside the cell is higher than outside, water will move into the cell, and when the concentration is higher outside, water will leave the cell.
What gas will diffuse faster He or Ne?
Helium (He) will diffuse faster than Neon (Ne) because helium has a lower atomic mass and smaller atomic size, making it lighter and easier to move through a medium.
What is the effect of osmosis on the mass of potato?
In osmosis, water moves from an area of high water concentration to an area of low water concentration through a semi-permeable membrane like the cell wall of a potato. If the external solution has a higher solute concentration than the potato cells, water will move out of the cells, causing them to lose mass. If the external solution has a lower solute concentration, water will move into the cells, causing them to gain mass.
Why does water pass through clay so slow?
Water passes through clay slowly because clay particles are very small and closely packed together, creating a fine network of pores. These pores restrict the flow of water, causing it to move through the clay with difficulty. Additionally, clay is highly cohesive and has a high water-holding capacity, further impeding water movement.
What are the differences in the way water molecules move in cold room temperature and in hot water?
In cold room temperature, water molecules move slower and are closer together due to lower kinetic energy. In hot water, molecules move faster and have more kinetic energy, causing them to spread out and move more freely. This difference in movement affects the density, viscosity, and behavior of water in each temperature condition.
Why is it easier to walk through air than through water?
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.
Is it easier for a boat to move through salt water or fresh water?
It is generally easier for a boat to move through salt water than fresh water due to the higher density and buoyancy of salt water. The increased buoyancy helps support the weight of the boat, reducing the amount of energy required to move through the water. Additionally, the viscosity of salt water is slightly lower, which can also contribute to easier movement. However, factors like water currents, wind, and the type of boat can also influence performance.
Why can a fish move through the water easier than a human?
their fins and other physical features are thinned, unlike humans. Humans, in comparison to fish, have much bulkier limbs than fish. Water is able to move/glide past the fish body parts easier.
Why do items fall through water easier than oil?
Becaus oil is thicker and heavier than water
Is it true that sound travels more slowly in air than in water?
No, sound travels faster in water than in air because water is denser than air. Sound waves move faster through denser mediums because the molecules are closer together, allowing the vibrations to travel more effectively.
Why can you hear sound better in air than under water?
cause its easier for sound waves to travel through air than through liquid
Why is it more difficult to move through water in a swimming pool?
No harder than it would be to move through water elsewhere.
Why does objecs move faster in hot water than in cold water?
Heat is the vibration of atoms, so atoms move faster. That's why you can clean things easier in hot water and why smells travel faster in a warmer room.
Why does water move more slowly through clay than through humus?
Clay has very small pore spaces
Why is turning a door knob easier than turning an axle?
Because the torque is less. The door knob has less to move, through a smaller resistance, than an axle, which usually turns a wheel to move (for example) a car.
Does sound move through water?
Sound moves through water. It just moves more quickly than in air, so it's harder for humans to identify it.
How does sound move through water easily?
because there are more particles in water than air but there are more in solids than water so sound travles further in solids than liquids ore air
