Torricell 's barometer used mercury . Pascal duplicated it using French wine of density 984kgm^(-3) . Determine the height of the wine column for nirmal atmospheric pressure.

A cup contains some mercury in it. Now a narrow glass tube is lowered in the mercury. After some time the mercury level in the tube becomes lower than the mercury level outside the tube as shown in diagram. During this process (Choose correct statements)

A manometer reads the pressure of a gas in an enclosure as shown in figure (a) When a pump removes some of the gas , the manometer reads as in figure (b). The liquid used in the manometers is mercury and the atmospheric pressure is 76 cm of mercury. (a) Give the absolute and gauge pressure of the gas in the enclosure for cases (a) and (b) , in units of cm of mercury. (b) How would the levels change in case (b) if 13.6 cm of water (immiscible with mercury) are poured into the right limb of the manometer ? (Ignore the small change in the volume of the gas).

Assertion:- If barometer is acceleratated upwards, the level of mercury in the tube of barometer will decrease. Reason:- The effective value of g will increase, so upthrust increase.
