Why the air resistance decrease the acceleration on falling object?
Drop a pound of feathers (in a bag) and a pound of lead from a height. The smaller mass of the lead will let it fall faster due to less air resistance, than the greater mass and much greater air resistance of the feathers.
How does a hot-air balloon rise?
The upthrust on the balloon is greater than the weight of the balloon. Thus, it rises upwards. The upthrust on the balloon is greater than the weight of the balloon because the air inside it has a lower density than the surrounding air.
Is the velocity of light higher in water or in air?
It's greater in air than in water.
Does air have more or less pressure than still air?
Yes, it has more pressure than still air because it has a greater force.
What does water have that is greater than air which causes sound waves to travel faster in water than in air?
Bulk modulus.
How much volume equals one kilogram?
That depends on the substance that the kilogram is made of. A kilogram of air has a large volume. A kilogram of water has a medium volume. A kilogram of lead or stones has a small volume.

How many cc are in a kilogram?
That depends what substance you have a kilogram of.A kilogram of air fills many many cc.A kilogram of water fills only 1,000 cc (1 liter).A kilogram if ice fills a few more cc than a kilogram of water does.A kilogram of lead, gold, or rock fills only a small number of cc.
What is Universal conversion between weight and volume?
There is none. Consider a kilogram of air and a kilogram of lead. The two will have considerably different volumes.
Is lead more dense than air?
Lead is more dense than air.
Is The air density in Atlanta lesser or greater than the air density in Colorado?
greater
Is the density of air is greater or less than 1?
greater
Why does a kilogram of sand takes up much less space than a kilogram?
A kilogram of sand takes up much less space than a kilogram of feathers because sand is denser than feathers. Density refers to how much mass is contained in a given volume. Since sand particles are heavier and more compact than feathers, they occupy less space for the same mass.
What weighs more lead or air?
lead which is element of non metal is heavier than air
Why does cold air have a greater volume than hot air?
It does not so there can be no answer to your question.
When an object or liquid's density is greater than one it wiLL BE WHAT?
The answer will depend on the units used. A density of 1 gram per litre is pretty light (less than the density of air at STP) whereas a density of 1 kilogram per ml is seriously dense.
When the air pressure in the lungs is greater than the air pressure outside the body you?
at higher altitudes the pressure of air is greater in our lungs as compare to the air pressure outside the body
