Answer the following :
At the sea level the atmospheric pressure 101 x 10^3 Pa is acting on a table top of size 1 m^2 . Under such a heavy pressure , why doesn't the table top crumble down ?

State whether the following statement are True or False : Atmospheric pressure at sea level is about 10^5 (dyn e)/(cm^2)

1.0 kg of liquid water is boiled at 100^@C and all of it is converted to steam. If the change of state takes place at the atmospheric pressure (1.01 xx 10^5 Pa ), calculate the energy transferred to the system , Given , the volume of water changes from 1.0 xx 10^-3 m^3 in liquid form to 1.671m^3 when in the form of steam.

1.0 kg of liquid water is boiled at 100^@C and all of it is converted to steam. If the change of state takes place at the atmospheric pressure (1.01 xx 10^5 Pa ), calculate the change in the internal energy of the system. Given , the volume of water changes from 1.0 xx 10^-3 m^3 in liquid form to 1.671m^3 when in the form of steam.

If the change of state takes place at the atmospheric pressure (1.01xx10^5 Pa) ,calculate the change in the internal energy of the system.Given,the volume of water changes from 1.0xx10^(-3 )m^3 in liquid form to 1.671m^3 when in the form of steam.

For air at room temperature the atmospheric pressure is 1.0xx10^(5)Nm^(-2) and density of air is 1.2 Kg m^(-3) . For a tube of tength 1.0 m closed at one end the lowest frequency generated is 84 Hz. The value of gamma (ratio of two specific heats) for air is

Water is filled in a flask up top a heightof 20 cm. The bottom of the flask is circular with radius 10 cm.If the atmospheric pressure is 1.01xx10^5 Pa, find the force exerted by the water on the bottom. Take g=10 ms^-2 and density of water = 1000 kgm^-3 .

What is the pressure at the bottom of the ocean at a place where it is 3 km deep ? [atmospheric pressure =1.01 xx10^(5)Pa, Density of sea water =1030kg m ^(-3)]

Solve the following example : The metal block has dimensions 10 cm xx 5cm xx 2cm and the density of to metal is 8 xx 10^3 kg//m^3 . It is kept on a table with the face 10 cm xx 5cm in contact with the table. Find the force and pressure exerted by the block on the table. (g = 9.8 m//s^2)

What is the pressure on a swimmer 10m below the surface of lake? g=10ms^(-2) , atmospheric pressure = 1.01 xx 10^(5)Pa
