Law tube where it will react with ammonia effusing from the other end. If ammonia is found to effuse just over twice as fast (2.17 times as fast to be exact), which was the acid gas? Answer: HBr Problem Club Question KK. Calculate the average speed of (a) a chlorine molecule at 25 oC; (b) an argon atom at -25 oC. Answer: (a) 324 m/s (b) 393 m/s
The manometer is also a device for measuring pressure and also works on the principle of using a liquid to calculate the difference in pressure in the tube and out of it. How a manometer works? The tube of the manometer is in “U” shape and the liquid can be either water or mercury (preferably mercury, since it has higher density and it's ...
