Question : An eudiometer measures
Option 1: atmospheric pressure
Option 2: time
Option 3: volume of gases
Option 4: vapour pressure
Correct Answer: volume of gases
Solution : The correct option is the volume of gases .
The volume of a gas mixture changes after a physical or chemical change, and a eudiometer is a laboratory instrument that monitors this change. It typically comes in two sizes, 50 mL and 100 mL, and in general, it resembles a graduated cylinder. The bottom end is submerged in water or mercury, while the top end is closed. In the cylinder, the liquid catches a sample of gas, and the graduation makes it possible to calculate the volume of the gas.
