Variation of Atmospheric Pressure with Altitude.
- remains unchanged
It is given that both liquid A and liquid B exert the same amount of pressure. The density of liquid A is twice the density of liquid B. The height of the column of liquid B is 10 cm. Then what would be the height of the column of liquid A?
None of the above
In high air pressure, the molecules are
hot and moving rapidly
warm and moving slow
close together and moving slowly
far apart and moving fast
If the pressure of a liquid column at its bottom is 1000 Pa and height of the liquid is 20 cm, the density of the liquid is (keeping in mind the gravitational pull of earth)
50 g cm-3
100 g cm-3
0.2 g cm-3
.5 g cm-3
Choose the correct option(s)
When the temperature of air in over a region increases:
Density of air decreases
Density of air increases
Atmospheric pressure reduces
Atmospheric pressure increases
Amount of pressure of liquid increases with
In high-pressure air, the molecules are _______ than in low-pressure air.
What is the pressure measured relative to atmospheric pressure and which is less than atmospheric pressure?
If the density of a liquid is 20 g cm-3, height is 4 cm and the gravitational field strength is 10 N kg-1, the pressure at the bottom of the liquid is
