What else can I help you with?
Is The air density in Atlanta lesser or greater than the air density in Colorado?
greater
Does air with greater density contain more or less molecules than less dense air?
Yes, given the same volume of both.
Why the density of air is greater on ground than top of mountain?
The density of air is greater at ground level because of the weight of the air above pressing down. As you go higher in altitude, there is less air above exerting pressure, leading to lower air density at the top of a mountain.
Is Density of helium balloon is greater or less than air?
The density of a helium balloon is less than that of the surrounding air. This is why helium balloons float in the air. Helium is lighter than the nitrogen and oxygen that make up the majority of Earth's atmosphere, so it provides buoyancy for the balloon.
How does cold air effect the density of gas?
'Cold' air will have less volume so the density is greater.
When you compare the density of water or air with another object how can you tell which has the lower or higher density?
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
Will a gas with a vapor density of 1.2 float or sink in air?
A gas with a vapor density less than 1 will float in air, while a gas with a vapor density greater than 1 will sink. Since the vapor density of the gas is 1.2, it will sink in air.
Why is the terminal velocity in water less than the terminal velocity in air?
More resistance, caused by a greater density.
Why wont a blloone with carbon dioxide float?
To float in air, the density of the balloon (divide the combined mass of balloon + contents by its volume) must be LESS than that of the same volume of air. If the gas inside the balloon has a greater density than air, the combined object (balloon + contents) won't have less density than air, either.
Why a sealed bottle partially filled with a liquid can float in a basin of the same liquid?
The buoyant force acting on the bottle is greater than its weight due to the displaced liquid inside. This causes the bottle to float, as the weight of the displaced liquid is greater than the weight of the bottle. This phenomenon is known as buoyancy and follows Archimedes' principle.
Compare the density of water and air?
Water is denser than air. The density of water is about 1000 kg/m^3, while the density of air at sea level is about 1.2 kg/m^3. This is why objects float in water but fall in air.
How do you think the density of heated air compares to the density of cooler air?
The density of heated air is less than the density of cooler air.
