What are organs that expand to fill with air?
do you mean fills with air? if so then its the lungs
Does the chamber of a barometer expand or contract as the air pressure goes up?
EXPAND
Why do your luns expand and contract?
to pull in air and break out air
Which is produced when warm air mass pushes a colder air mass?
An Warm air mass
How does the temperature of the air molecules change at each level of the atmosphere?
The air molecules expand as it gets higher and higher into the atmosphere. the molecules expand.
Does water expand faster than air?
If you apply a given amount of energy to a sample of liquid water (or even gaseous) and an equal mass of air, the air will expand more rapidly than the water (it has a lower specific heat).
The volume of air change without changing its mass why?
No. If the volume of air changes, so will its mass.
What effects on density of air if tempecture increase?
A gas (including air) will expand if the temperature increases. That means the same mass of gas will have a larger volume. Since density is mass / volume, that means the density will decrease.
Is it possible for colon polyps to rupture during air travel due to air pressure?
No they can not. A polyp is a solid mass. It is not filled with gas and therefore will not expand in a low pressure environment.
What is a large body of air with relatively uniform properties?
This is an air mass.
How does air heat?
it causes air to expand
How air heat?
it causes air to expand
Why do solids expand when heated even though their mass does not change?
BECAUSE the moncules are heated they expand because there gay and expand
When air gets warmer does it get bigger or smaller?
Read about "Boyles law" http://www.grc.nasa.gov/WWW/K-12/airplane/aboyle.html As temperature increases the volume OR the pressure of a mass of air will increase. If the volume of the air mass is constrained (inside a container of fixed size) the pressure will go up. If the mass of air is allowed to expand freely it will become less dense (lighter per unit volume)
How does a balloon expand?
when you fill a balloon with air the air makes pressure. the air pressure maximizes the balloon fabric allowing the balloon to expand.
How does heat affect air?
it causes air to expand
When fluids expand when they are heated does their density increase?
No. Remember that density is a ratio of mass compared to volume. If the volume increases without adding more mass, then the density would decrease. This is why hot air balloons rise.
