Examples of pneumatic trough in the following topics:
-
- This arrangement is called a pneumatic trough, and it was widely used in the early days of chemistry.
- O2 gas is collected in a pneumatic trough with a volume of 0.155 L until the height of the water inside the trough is equal to the height of the water outside the trough.
- How many moles of oxygen are present in the trough?
- Oxygen gas generated in an experiment is collected at 25°C in a bottle inverted in a trough of water.
- When the water level in the originally full bottle has fallen to the level in the trough, the volume of collected gas is 1750 ml.
-
- The pig iron was melted in a running-out furnace and then run out into a trough.
- This process oxidized the silicon to form a slag, which floated on the iron and was removed by lowering a dam at the end of the trough.
-
- This image shows the anatomy of a sine curve: the crest is the peak of each wave, and the trough is the valley; the amplitude is the distance between the crest and the x-axis; and the wavelength is the distance between two crests (or two troughs).
-
- Wavelength is defined on the left below, as the distance between adjacent peaks (or troughs), and may be designated in meters, centimeters or nanometers (10-9 meters).
-
- If a crest of one wave meets a trough of another wave, then the magnitude of the displacements is equal to the difference in the individual magnitudes; this is known as destructive interference.
