Question about it.
00:04
Explain why scuba drivers should never hold their bread when they ascend to the surface.
00:14
So the main reason is because this might cause a damage to the launch as a result increase in volume of hair in the launch.
00:55
So to explain this, i let's say here, water here, the atmosphere.
01:13
For every 10 meter deep into water, the diver express additional one atmosphere.
01:24
So as the diver descend down, down into the water, the pressure increase.
01:37
Let me say p pressure increase in this direction.
01:45
Where are the volume increase like this? this is following.
02:01
We know the relationship between pressure at pv equals an rt.
02:08
So p equals nrt for v.
02:13
So it's like p is a faster property to v.
02:17
So when pressure increase, volume decrease.
02:23
So that's it.
02:25
So if a diver is at this level, at this water level, the moment it descends down into the water, the diver will experience increase in pressure as a result of the weight of water that is being displaced.
02:48
So if a diver is air, and let's say this is from air to air...
