Question
The height of the Mercury column in the Toricelli barometer is h = 760 mm here on Earth at sea level.
What would be the height of the Mercury column on the surface of the Moon? (The Moon has no atmosphere, and the gravitational field is six times weaker there than here on Earth.)
A) 127 mm, six times shorter.
B) 0 mm.
C) 760 mm, same as on Earth.
D) 4560 mm, six times higher.
I already guessed A and C both were wrong.
What would be the height of the Mercury column inside a Moon-base where an Earth-like air atmosphere is maintained for comfortable living?
A) 760 mm, same as on Earth.
B) 4560 mm, six times higher.
C) 127 mm, six times shorter.
D) 0 mm.
I already guessed A it was wrong.
Explanation / Answer
Answer B)
As at moon there is no atmosphere so there won't be atmospheric pressure so the height in mercury coolumn will be zero in case 1
Answer B)
Now if we maintain atmosphere we can not change gravity force so there is 6 time less gravity force so for maintaing the the atmospheric pressure same as earth mercury will rise 6 times heigher because afterall product of density* gravity* height should be same as earth so if gravity derease 6 time height will increase 6 times.
