The blood pressure at the feet is more than the blood pressure at the head. Give reason.

What happens when a pressure greater than the atmospheric pressure is applied to pure water or a solution?

A ladder is at rest with its upper end against a wall and the lower end on the ground. Is the ladder more likely to slip, when a man stands on it at the bottom or a the top? Give reason.

Explain why (a) The blood pressure in humans is greater at the feet than at the brain

Explain why Atmospheric pressure at a height of about 6 km decreases to nearly half of its value at the sea level, though the height of the atmosphere is more than 100 km

A manometer reads the pressure of a gas in an enclosure as shown in Fig. 10.25 (a) When a pump removes some of the gas, the manometer reads as in Fig. 10.25 (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 with mercury)

Explain why The size of the needle of a syringe controls flow rate better than the thumb pressure exerted by a doctor while administering an injection

The gas phase decomposition of acetaldehyde, CH_3CHO(g) rarr CH_4(g)+CO(g) at 680K is observed to followed the rate expression: Rate -d[CH_3CHO]/dt=k[CH_3CHO] ^(3/2) IF the rate of decomposition is followed by monitoring the pantial pressure of actetaldehyde, we can express the rate as. dP_(CH_3CHO//dt)=k[P_(CH_3CHO]^ (3/2) If the pressure is measured in atomospheres and the time in minutes than What are the units of the rate of reaction?

During blood transfusion the needle is inserted in a vein where the gauge pressure is 2000 Pa. At what height must the blood container be placed so that blood may just enter the vein? [Use the density of whole blood from Table 10.1]

The vapour pressures fo pure liquids A and B are 450 mm Hg and 700 mm Hg respectively at 350K. If the total vapour pressure of the mixture of the two liquids at 350K is 600mm Hg, Calculate the more fractions of the two components in the solution. Also, calcuate the partial pressures of the two components in the vapour phase.
