What causes your skin to turn pink when you are hot?
When you get hot, your blood flow increases and your blood vessels also get closer to the surface of your skin to allow the air to help you cool down. That is why your skin appears pink; your blood is closer to the surface.
Why do sound waves travel faster in denser substances?
Molecules are packed closer together, hence electrons are also closer together and it is the electrons that do the transmitting!!!!
How large a room of air is packed into a basketball at 8psi?
The answer depends on the pressure when the air is let out of the basketball.
How tightly packed the magnetic lines tells us?
The closer the magnetic field lines, the stronger the magnetic force in that area.
Why do the bubbles exhaled by a scuba diver grow as they aproach the surface of the ocean?
as the bubbles get closer to the surface, there is less water pressure on them therefore allowing them to expand.
Why is there most air closer to the surface?
because warm air move upwards and cool air due to gravity move closer to the earth surface
Why does cold air exerts more pressure then the warm air?
Because the air molecules are packed closer together in cold air.
Are air particles more closely packed near earth surface or high above?
yes
Is it warmer underground or on the surface?
well because of the sufuce of the earth and it is closer to cold air i would say on the surface
What is molecules closer to the surface that are more densely packed than those higher in the atmosphere because of gases pressing down from higher in the atmosphere?
Atmospheric pressure
What is icobar?
If you meant isobar - An isobar is a line on a map showing air pressure. the closer the isobars are packed together, the lower the pressure, and stronger the wind is.
How is air pressure effected by altitude?
With a higher altitude, there is a lower air pressure. This is caused by gravity pulling the gas molecules of our atmosphere closer to its surface. when the molecules are farther away from the Earth's surface the gravitational pull is weaker thus making the atmosphere thinner higher up and thicker closer to the surface.

What are Molecules closer to the surface are more densely packed than those higher in the atmosphere because of the mass of gases pressing down from higher in the atmosphere?
Im pretty sure its atmospheric pressure
Explain what hppens to air pressure as you move away from the earths surface?
Pressure increases as you get closer to earth.
Why is air pressure greatest at the Earth's surface?
Because as you get closer to the surface of the earth, the more air that is on top of you. At the top of the atmosphere, there is no air, and everything is a vacuum, where you have no weight. When you get close to the earth, the weight of the air builds until it when you're at the very lowest point of the earths surface, all the air in the atmosphere above you is pressing down.
What happens to the volume of air in your lungs when you ascend to the surface of the ocean?
The air in your lungs expands in volume as you get closer to the surface of any water you swim in. This is because the air was compressed when deeper due to the pressure of the water around you. This is why when scuba divers always exhale while ascending to avoid rupturing their lungs as the air expands.
