Pressure is what makes the gas molecules to occupy less volume. Without any atmospheric pressure, which is quite huge (101.3 KPa), the molecular separation of the air molecules would be very huge. This is testified by Boyle's Law PV=constant. If P is very small, inversely, V would be very huge. Therefore, a small mass of air would occupy a huge volume.

How does atmospheric pressure affect the boiling point of matter?
Atmospheric pressure exerts pressure on the molecules of the liquid, confining them. In order to boil, the electrons must be excited, but must become hotter to overcome the pressure of the atmosphere. Therefore, pressure makes a liquid boil at a higher temperature. With a solid, the molecules are already compact together and have to be melted before they can be boiled. This does not require excitation of electrons, but it does require movement of electrons. Once the solid is melted, pressure will make it harder for the electrons to become excited.
Why does water boil when the vapor pressure is equal to atmospheric pressure?
Water boils when its vapor pressure equals atmospheric pressure because at this point the molecules in the liquid have enough energy to escape into the gas phase, creating bubbles and causing the liquid to boil. This balance of vapor pressure and atmospheric pressure allows the liquid to change into a gas at a constant temperature.
Is the pressure inside the balloon equal to the atmospheric pressure?
Think about this: if the pressure WERE equal, what would happen in the instant when you open the neck of the balloon and whatever pressure is on the inside meets the pressure that is on the outside (atmospheric pressure)? In your experience, what DOES happen?
When the vapor pressure of a liquid is equal to the atmospheric pressure the liquid .?
it begins to boil - Monsy
In a pressure cooker a lid is screwed tightly onto a pot so that the air pressure in the pot is increased What effect if any will this have on the boiling point of water in the pot?
Increasing the air pressure in the pot will raise the boiling point of water. This is because with increased pressure, water molecules require more energy to overcome the higher pressure and vaporize, leading to a higher boiling point than at normal atmospheric pressure.
What effect does atmospheric pressure have on your body?
Absolutely nothing
What would earth's atmospheric pressure be if earth's atmosphere contained twice as many molecules as is does today?
If Earth's atmosphere contained twice as many molecules as it does today, the atmospheric pressure would also double. This is because pressure is directly related to the number of gas molecules in the atmosphere.
What effect does increase water vapor have on atmospheric pressure?
it causes a decrease in atmosperic pressure A+
What three things affect airpressure?
Heat, number of molecules, atmospheric pressure and volume Volume * Pressure = molecules * molar gas constant * Heat
Which two qualities affect atmospheric pressure?
Temperature and altitude are two qualities that affect atmospheric pressure. As temperature increases, air molecules move faster and create higher pressure. At higher altitudes, there are fewer air molecules above, leading to lower pressure.
Does low pressure weather effect migraine?
Atmospheric pressure changes can trigger Migraine in some patients.
Which factor causes atmospheric pressure?
Atmospheric pressure is primarily caused by the weight of air above a specific point on the Earth's surface. Gravity pulls air molecules towards the Earth, creating a force that results in atmospheric pressure.
Why does atmospheric pressure decrease with altitude?
Atmospheric pressure decreases with altitude because there are fewer air molecules higher up in the atmosphere, leading to lower air density and less pressure exerted by the air above.

Does atmospheric pressure have any effect on the oxygen level in the scuba tank?
No, only when it is released into the atmosphere at the ambient pressure.
What is the name for pressure caused by the weight of the atmosphere?
Simply put, atmospheric pressure is the force exerted on a measuring point by the weight of the air molecules on top of that point. Standard atmospheric pressure, measured at sea level at 59F or 15C, is used as a reference point and is equal to 29.92 inches of mercury or 1013 millibars of pressure.
How did pressure effects the sound when temperature is constant?
The atmospheric pressure has no effect on the speed of sound when the temperature is constant. The air pressure has no influence on the sound.
