Air balloon ? pressure in water @MR. INDIAN HACKER @Crazy XYZ #theexking #shorts #experiment

A narrow capillary tube is dipped 10 cm below water surface and a liquid bubble of radius 2 mm formed at the lower end by blowing air through the tube. a. Calculate the excess pressure due to surface tension. b. What is the pressure required in the tube in order to blow a hemispherical bubble at its end in water? The surface tension of water at temperature of the experiment is 7.30xx10^(-2) N//m . 1 atmospheric pressure = 10^(5) Pa , density of water = 1000 kg//m^(3)

The air inside a balloon exerts pressure in ………….. direction.

Statement-1: Weight of a empty balloon measured in air is w_(1) . If air at atmospheric pressure is filled inside balloon and again weight of balloon is measured. Weight of balloon is w_(2) is second case. Then W_(2) is equal to w_(1) Statement-2: Upthrust is equal to weight of the fluid displaced by the body.

Relative humidity of air is 60^(@)C and the saturation vapour pressure of water vapour in air is 3.6kPa . The amount of water vapours present in 2 L air at 300 K is

Relative humidity id defind as the ration of partial pressure of water in air at a given temperature to the vapour pressure of water at that that temperature Calculate the mass of water per litre air at (a) 20^(@)C and 45% relative humidity (b) 0^(@)C and 95% relative humidity (c ) Discuss wether temperature or relative humidity has the greater effect on the mass of water vapour in air Given P_(H_(2)O)^(@) =17.5 torr at 20^(@)C and 4.58 torr 0^(@)C .

A spherical balloon contains air at pressure P_(1) and is placed in vacuum. It has an initial diameter of D_(1) . The balloon is heated until its diameter becomes D_(2) = 2D_(1) . It is known that pressure in the balloon is proportional to its diameter. Calculate the work done by the gas in expansion.

An air bubble of radius r in water is at a depth h below the water surface at some instant. If P is atmospheric pressure, d and T are density and surface tension of water respectivley . the pressure inside the bubble will be :

A cylindrical vessal is filled with water as shown in the figure .Calculate the difference in pressure due to water at points A and B .(Pressure due to air is negligible ,density of water =1 g cm^(-3))
