To solve the problem, we will use Boyle's Law, which states that the pressure of a gas multiplied by its volume is a constant when the temperature is held constant. The formula is given by: \[ P_1 V_1 = P_2 V_2 \] Where: - \( P_1 \) = initial pressure - \( V_1 \) = initial volume - \( P_2 \) = final pressure ...

A mercury barometer reads 75cm. Now 3 cm^(3) of atmospheric air is introduced into the tube. The mercury falls to a height of 65 cm and the length of air column above the mercury is found to be 15 cm Calculate the cross-sectional area of the barometer tube.

A barometer tube is 1 m long and 2cm^(2) in cross section. Mercury stands to a height of 75cm in the tube. When a small amount of oxygen is introduced in the space above the mercury level, the level falls by 5cm. Calculate the mass of the oxygen is introduced. Room temperature= 27^(@)C , g=10 m s_(-2) and density if mercury = 13600kg m^(-3) .

The mercury manometer consists if two unequal arms of equal cross section 1 cm^(2) and lenghths 100cm and 50cm. The two open ends are sealed with air in the tube at a pressure of 80cm of mercurey. Some amount of mercury is now introduced in the manometer through the stopcock connected to it. If mercury rises in the shorter tube to a lenght 10cm in steady state, find the length of the mercury column risen in the longer tube.

A faulty barometer contains certains amount of air and saturated water vapour . It reads 74.0cm when the atmospheric pressure is 76.0cm of mercury and reads 72.10cm when the atmospheric pressure is 74.0cm of mercury.Saturation vapour pressure at air temperature =1.0cm of mercury. Find the length of the baromerer tube above the mercury level in the reservoir.

A barometer tube reads 76 cm of mercury. If the tube is gradually inclined keeping the open end immersed in the mercury reservoir, will the length of mercury column be 76 cm, more than 76 cm or less than 76 cm?

A barometer tube reads 76 cm of mercury. If the tube is gradually inclined at an angle of 60 with vertical, keeping the open end immersed in the mercury reservoir, the length of the mercury column will be

A barometer correctly reads the atmospheric pressure as 76cm of mercury. Water droplets are slowly introduced into the barometer tube by a dropper. The height of the mercury column first decreases and then become constant. If the saturation vapour pressure at the atmospheric temperature is 0.80cm of mercury, find the height if the mercury column when it reaches its minimum value.

A barometer tube is 80 cm long (above the mercury reservoir). It reads 76 cm in a particular day. A small amount of water is introduced in the tube and the reading drops to 75.4 cm. Find the relative humidity in the space above the mercury column if the saturation vapor pressure at the room temperature is 1.0cm.

A column of mercury is in the middle of horizontal tube of uniform cross section closed at both ends. The pressure of the enclosed air column on either side of the mercury is 75 cm of mercury column. When the tuve is placed vertical the length air below the mercury column is (3)/(5) th of that above it. if length of mercury column is 10n cm. find n.

In the given figure, atmospheric pressure p_0 = 1 atm and mercury column length is 9 cm. Pressure p of the gas enclosed in the tube is
