If the compressibility of water is `sigma` per unit atmospheric pressure then the decrease in volume V due to P atmospheric pressure will be

If the compressibility of water is sigma per unit atmospheric pressure, then the decrease in volume V due to atmospheric pressure P will be

If the compressibility of water is sigma per unit atmospheric pressure, then the decrease in volume V due to atmospheric pressure P will be

The unit atmospheric pressure is:

Unit of atmospheric pressure is

The compressibility of water is 4xx10^-5 per unit atmospheric pressure. Calculate the decrease in volume of 100cm^3 of water under a pressure of 100 atmosphere.
