Atmospheric Pressure

Why does the weather changes with latitude?
 

The  steady mercury level of the barometer indicates _____ weather.

A closed-end manometer was attached to a vessel containing argon. The difference in the mercury levels in the two arms of the manometer was $12.2 \mathrm{cm}$. Atmospheric pressure was $783 \mathrm{mm} \mathrm{Hg}$. Calculate the pressure of argon.

The pressure of a gas in the open end of a close end manometer is equal to the pressure of the column of mercury _____.

A close end manometer is connected to a gas cylinder at the open end.If the difference of the level of mercury in two limbs is $10 \mathrm{mm}$, then  the pressure of the gas in the cylinder is 

Explain the working of close tube manometer.

How a coastal location of a place affects its weather?

A sudden drop of mercury leven of the barometer indicates:

What are the conditions that determine the weather?

How the height of the atmosphere can be calculated by the density of air? Establish the required expression.

Why the atmosphere is homogeneous?

In a barometer, the mercury level is $76 \mathrm{cm}$ at sea level. On a hill of height $3 \mathrm{km},$ if the ratio of density of $\mathrm{Hg}$ to that of air is ${10}^4$, the atmospheric pressure on the hill is

Air separated from the atmosphere by a column of mercury of length $\text{h}=15\text{cm}$ is present in a narrow cylindrical two soldered at one end. When the tube is placed horizontally the air occupies a volume $V_1=240{\text{mm}}^3$ . When it is set vertically with its open end upwards the volume of the air is $V_2=200{\text{mm}}^3$ . The atmospheric pressure during the experiment is $7\text{n}\text{cm}$ of $\mathrm{H}\mathrm{g}$ where $n$ is single digit number. Find $n$.

At what speed will the velocity of a stream of water be equal to $20 cm$ of mercury column? (Taking, $g=10 m{s}^{-2}$ )

A open U-tube contains mercury. When $11.2 \mathrm{cm}$ of water is poured into one of the arms of the tube, how high dose the mercury rise in the other arm from its initial unit?
