Measuring Pressure With Barometers and Manometers

The video tutorial explains the concept of air pressure, how it is measured using barometers and manometers, and the principles behind these devices. It covers the composition of air, the concept of atmospheric pressure, and how it decreases with altitude. The tutorial details the use of mercury in barometers to measure atmospheric pressure and introduces manometers for measuring gas pressure in closed and open systems. Practical applications of these measurements in chemical reactions are also discussed.
