Air Pressure on Water | Fun with Science Demo #shorts #physics

Define science in short.

An air bubble doubles its radius on raising from the bottom of water reservoir to the surface of water in it. If the atmosphetic pressure is equal to 10 m of water, the height of water in the reservoir will be

Write a short note on different branches of physics .

The pressure of confined air is p. If the atmospheric pressure is P, then :-

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

Which of the following statements are incorrect? A) Changes in air temperature have no effect on the speed of sound. B) Changes in air pressure have no effect on the speed of sound. C) Changes in air pressure have effect on the speed of sound. D) The speed of sound in water is lower than in air

Assertion: An air bubble in water grows in size when it rises from bottom to top. Reason: On moving from bottom to top, pressure of the air bubble will decrease, volume will increase and hence, size of air bubble will rise.

On a certain humid day, the mole fraction of water vapour in air at 25^(@)C is 0.0287. If total pressure of air is 0.977 bar, calculate the partial pressure of water vapour in air and relative humidity if vapour pressure of water at 25^(@)C is 0.0313 bar.
