Yes, the pressure inside a bubble is greater by the amount 4*sigma/R where sigma is the surface tension and R the bubble radius. This is also known as a Laplace pressure, discovered by the French scientist Pierre Simon de Laplace. The factor of 4 comes from the fact that the bubble has two sides, both of which exert a force on the air inside.

Air pressure is greater at point?
B
Will the speed of a wind be greater if the difference in air pressure is large or small?
no it will not be greater are greater it does not matter
Would the pressure be greater at the top of a mountain or at the bottom of it?
At the bottom. You can think of the air pressure at a given location as being the weight of all the air in a column above it. Thus, the higher you go, the less air there is above you, and thus the lower the air pressure. In the extreme, when you rise out of the athmosphere, there is no air above you at all, and the air pressure is effectively zero - a vacuum. Air pressure is greater at the bottom of a mountain.
How airplanes can fly in air in spite of being heavier than air?
The air pressure under the wings is greater that the pressure over the wings creating lift.
Would air pressure be greater over the ocean or over land?
Early in the day, the land is quite cold as it has lost its heat overnight. Therefore it is more dense and has a greater air pressure. However, as the day progresses, the air above the land will be very hot, less dense, and hence have a lower pressure. As a result, the air above the ocean has a greater air pressure later in the day.
When the air pressure in the lungs is greater than the air pressure outside the body you?
at higher altitudes the pressure of air is greater in our lungs as compare to the air pressure outside the body
How does the density of the air affect pressure?
Pressure affects the density of air by increase of pressure increases the density
Which air has greater air pressure?
Cooler air has greater air pressure since the air molecules are denser, meaning they are close together. Warmer air has lower air pressure for the opposite reason.
How does altitude in the atmosphere affect air pressure?
The greater the altitude, the lower the air pressure.
Air pressure is greater at point?
B
Will the speed of a wind be greater if the difference in air pressure is large or small?
no it will not be greater are greater it does not matter
Is air pressure greater at the south pole why?
no they are equal
Where is air pressure greater in the exosphere or in trposphere?
Troposphere.
Where is the air pressure greater-at sea level or on a mountaintop?
Air pressure is Greater at sea level.Atmospheric pressure is higher at sea level. There is more atmosphere on top of the observer at that point, so the pressure is higher.
Where is air pressure weakest?
The lower you go into the sea level, the greater the air pressure. The higher you go above the sea level, the lower the air pressure.
When swimming under water pressure becomes greater?
Yes. The water pressure exerted on your body is greater than air pressure, and increases with depth.
Is air pressure greater at high altitudes or low altitudes?
It is greater at a lower altitude.
