  • Arrange the following steps in proper sequence to determine the pressure exerted by a gas enclosed in a container using a manometer. (a)Connect one end of the manometer to the container filled with gas. (b)Both the limbs of the manometer are exposed to air, mercury level in both the limbs are equal due to atmospheric pressure. (c )Determine the difference in level of the mercury in both the limbs of the manometer (l). (d) If the level of the mercury in the limb connected to the container is above the mercury level in the limb exposed to air, the pressure of the gas in the container is determined as atmospheric pressure -l. (e ) If the level of the mercury in the limb connected to the container is below the mercury level in the limb exposed to air, the pressure of the gas in the container is determined as atmospheric pressure +l. (f) Note the level of the mercury in the limbs of the manometer.
