Wiki User
∙ 10y agoWell yes. It is normally written the otherway round: the more molecules in a given volume of air, the greater the density.
Wiki User
∙ 6y agoNo, in general the higher you go in the atmosphere, the less dense the air.

Why the density decrees at higher altitudes?
the density decreases because their is more air pressure in lower altitudes and as you go up their is less air pressure making it hard to breath
Does high pressure have high density?
If you are referring to a high pressure gas, then yes. The higher the pressure, the higher the density of the gas because the molecules pack closer together. The density of liquids can also be affected by pressure but to much less of an extent. For most purposes, liquids such as water are considered incompressible.
Why does density of air decrease with increase in height?
The density of air decreases with increasing altitude because air at high altitudes is under less pressure.
Is air mass and air pressure the same thing?
No. An air mass is a section of the atmosphere with certain characteristics of temperature and humidity that distinguish it from nearby air masses. Air pressure is, in simple terms, how much the air is pressing down on the surface.
If you have two rocks rock A and rock B Rock A is bigger but has the same mass as rock B How will the density of the two rocks compare?
The density of rock B is greater because its volume is less.
Which exerts greater pressure on the floor standing flat footed or standing on tiptoe?
on tiptoe, because the force acts over less area
Which exerts greater pressure on the floor- standing flat footed or standing on tiptoe?
on tiptoe, because the force acts over less area
Which exerts greater pressure on the floor standing flat-footed or standing on tiptoe?
on tiptoe, because the force acts over less area
Is Saturn's density less or greater than earth's density?
Less
Dry air exerts less pressure than air that has What?
devin in it
Why is air pressure greater at sea level then it is one mile up in the air?
There is less air higher in the sky so the pressure is less. At sea level, all the air above a certain space exerts pressure. There's also more air, so the pressure is greater. Like any material, air becomes heavy in large enough quantities.
Is the density of air is greater or less than 1?
greater
Why does a pointed heal shoe exert less pressure?
Sorry - it exerts more pressure than a flt heel.
What is the rule that the faster a fluid movesthe less pressure the fluid exerts?
Bernoulli's principle
What effect does high density altitude as compared to low density altitude have on propeller efficiency and why?
Efficiency is reduced because the propeller exerts less force at high density altitudes than at low density altitudes. Less efficient slow plane
What is the effect of density on the buoyancy of an object?
greater density tends to less buoyancy
Why does a coin sink and a boat float?
An object will sink if it has greater density than water (or whatever liquid it is place in); it will float if it has less density than the liquid.An object will sink if it has greater density than water (or whatever liquid it is place in); it will float if it has less density than the liquid.An object will sink if it has greater density than water (or whatever liquid it is place in); it will float if it has less density than the liquid.An object will sink if it has greater density than water (or whatever liquid it is place in); it will float if it has less density than the liquid.
