Pressure Exerted by Liquids and Gases

Three identical vessels X, Y and Z contain same quantity of liquid. In each vessel, balls with different densities, but same masses are placed as shown in figure. If $F_x, F_y$ and $F_z$ are the total forces acting on the base of vessels X, Y and Z respectively, then

State whether the given statement is True or False. Correct the false statement.

Pressure of a liquid does not depend upon the size and shape of the container.

Blood pressure is measured using the device called _____.

Glycerine (density$=1.3\times {10}^3 \mathrm{kg} {\mathrm{m}}^{-3}$) is filled in a flask up to a height of $20 \mathrm{cm}$. The bottom of the flask is circular having a radius $8.0 \mathrm{cm}$. Calculate the liquid pressure and thrust acting on the bottom of the flask.
 

Which is higher - the air pressure in Mumbai or the air pressure on top of Mt Everest? Give reason.

Write true or false. Rewrite the statement correctly if it is false.
Air pressure increases as you go up in the atmosphere.

Pressure exerted by a liquid depends upon :

Justify the statement that liquid exerts equal pressure at the same depth in a static liquid.

What is the reason behind liquids exerting pressure on the walls of the container?

Ozone layer is present in between troposphere and stratosphere.

The layer which lies next to mesosphere _____.

Pressure exerted by water at the bottom of the container depends on the height of its water column.

What is suction and how is it used?

What is pressure? While making a dam, where should be a thicker wall required, at the top or at the bottom? Why is it necessary to make the dam like this?

Explain the process how the pressure exerted by the gases. Why makes a balloon get inflated when air is filled in it?

Define liquid pressure. Demonstrate an activity which shows liquids exert equal pressure at the same depth in static liquid.

Discuss an activity to show that a liquid exerts pressure on walls of its container.

What is mean by suction?

Why is pressure the same at the same depth?

As depth of water increases the pressure of water gradually increases.
