The atmospheric pressure on the moon is far less than 1.10-11 torr or mbar.
Earth: 2.5x1019 mol/cm3 (STP, 1 atm) Moon: ≈104 mol/cm3 day and ≈ 2x105 mol/cm3 night or approx. 10-14 of that found on Earth i.e. 10-14 torr.

Why is the atmospheric pressure on moon is zero?
The atmospheric pressure on the moon is essentially zero because the moon does not have a significant atmosphere. Unlike Earth, which has a dense atmosphere that exerts pressure due to the weight of the air above us, the moon lacks this gaseous envelope and thus has almost no atmospheric pressure.
Why can't we suck a cold drink through a straw on the moon?
Sucking through a straw relies on atmospheric pressure to push the liquid up. In the airless environment of the moon, there is no atmospheric pressure to assist in the suction action, making it impossible to drink through a straw.
What is a sentence with the word atmospheric pressure?
Atmospheric pressure
Why did astronauts need to wear space suits when they visited the moon?
There is no atomosphere or atmospheric pressure. Without atomspheric pressure the astronauts blood would boil.
What happens to water closest to the moon?
Water on the surface of the moon will rapidly turn to water vapor as there is no atmospheric pressure on the moon. The vapor will then escape the moon's gravity which is much weaker than the gravity on Earth.
Why is the atmospheric pressure on moon is zero?

How high is the atmosphreic pressure on the moon?
The atmospheric pressure on the moon is nearly zero (effectively vacuum).
Is there more or less atmospheric pressure on the moon than the earth?
Less.
Why can't we suck a cold drink through a straw on the moon?
Sucking through a straw relies on atmospheric pressure to push the liquid up. In the airless environment of the moon, there is no atmospheric pressure to assist in the suction action, making it impossible to drink through a straw.
Would a balloon rise in the absence of atmospheric pressure?
No. On the moon they just fall. (But it sure would expand !)
What is a sentence with the word atmospheric pressure?
Atmospheric pressure
What is an atmospheric tide?
An atmospheric tide is a collective name for the pressure waves in the atmosphere similar to the tides of the ocean produced by the gravitational influence of the moon and by thermal expansion and contraction.

There is no atomosphere or atmospheric pressure. Without atomspheric pressure the astronauts blood would boil.
What happens to water closest to the moon?
Water on the surface of the moon will rapidly turn to water vapor as there is no atmospheric pressure on the moon. The vapor will then escape the moon's gravity which is much weaker than the gravity on Earth.
Would a balloon rise in an atmosphere where the pressure was somehow the same at all altitudes Would a balloon rise in the complete absence of atmospheric pressure such as on the surface of the moon?
No
What is the total pressure gauge pressure plus atmospheric pressure?
Total pressure is equal to the sum of gauge pressure and atmospheric pressure. Atmospheric pressure is always present and contributes to the total pressure measurement.
To change from psig to psia you must add what to p.s.i.g?
You must add the atmospheric pressure.
