Water vaporizes under vacuum conditions. Mark the statement which is correct with respect to using water as a barometric fluid.
Statement 1: We can use water instead of mercury to construct a barometer for measuring the atmospheric pressure.
Statement 2: We do not use water in a barometer because it will be very inconvenient to use.
At what depth below the surface of water will pressure be equal to twice the atmospheric pressure? (Atmospheric pressure = 10 N/cm2, Density of water = 103 kg/m3, g =9.8m/s2)
