When you are changing a scale on a graphic, you warn the viewer by using a squiggle line on the changed axis. If the bar is unusually long, the bar length is compressed with a squiggle in the bar itself.
"Because the pressure will cause the heart to explode." Well, no (the heart cannot "explode" anyways, rupture yes, but I'll leave it at that for now). The main problem is the pressure differential on the surface compaired to the lungs which are submerged. At one meter's depth the water adds 0,1 bar of pressure to the atmospheres 1 bar. This means that the lungs which are compressed to 1,1 bar (1 bar ATM and 0,1 bar of water) must overcome the pressure, making breathing impossible since the air cannot be drawn into the lungs.
The rigid bar is not called a fulcrum! And, by the same token, why is the bar called a bar?
pie charts show the percentage of whatever the chart is displaying and bar charts show the improvement or difference in what the chart is showing. they are the same because if both the pie chart and bar chart are being used for the same situation, the data should be the same.
The bar over the letters tells you to mulitiply it by 1,000.
To avoid accumulation of moisture.
Believe it or not, we can die from too little oxygen AND too much oxygen. This concept involves partial pressures. If we first consider using standard air (i.e. 20% Oxygen and 80% Nitrogen): (1 bar = 1 kilogram of pressure per square centimetre) At the surface - Total Pressure of air = 1 bar - Pressure of Oxygen = 0.2 bar - Pressure of Nitrogen = 0.8 bar At 10m - Total Pressure of air = 2 bar - Pressure of Oxygen = 0.4 bar - Pressure of Nitrogen = 1.6 bar At 20m - Total Pressure of air = 3 bar - Pressure of Oxygen = 0.6 bar - Pressure of Nitrogen = 2.4 bar At 30m - Total Pressure of air = 4 bar - Pressure of Oxygen = 0.8 bar - Pressure of Nitrogen = 3.2 bar At 40m - Total Pressure of air = 5 bar - Pressure of Oxygen = 1.0 bar - Pressure of Nitrogen = 4.0 bar At 50m - Total Pressure of air = 6 bar - Pressure of Oxygen = 1.2 bar - Pressure of Nitrogen = 4.8 bar At 60m - Total Pressure of air = 7 bar - Pressure of Oxygen = 1.4 bar - Pressure of Nitrogen = 5.6 bar At 70m - Total Pressure of air = 8 bar - Pressure of Oxygen = 1.6 bar - Pressure of Nitrogen = 6.4 bar It is at the partial pressure of 1.6 bar (which occurs at 70m where oxygen becomes toxic. That is why most dive organisations recommend 50m as a maximum for recreational diving. However, if pure oxygen is used: At surface - Pressure of Oxygen = 1 bar At 10m - Pressure of oxygen = 2 bar The oxygen has already become toxic! Hope that answers your question. The concept is called "partial pressures" and "oxygen toxicity" if you want to research more on a search engine.
If the gas is normal air (~20-22% oxygen), the maximum recommended depth of most dive organisations is in the region of 50-60m. The reason for this is that the deeper you go, the higher the pressure of the water. For example, on the surface, the pressure is 1 bar, 10m is 2 bar, 20m is 3 bar 30m is 4 bar etc. Oxygen becomes toxic to the human body at about 1.6 bar so if you are at 70m, with a mix of 20% oxygen, you are at 8 bar of pressure. At 8 bar, the parital pressure of oxygen is 1.6 bar, enough to become toxic. So compressed air becomes dangerous at 70m so most organisations advise to go no deeper than 50-60m. If you use a different gas blend, such as Nitrox ar Trimix, the amount of oxygen is different so the depths are different too. In summary, on compressed air, the maximum is about 70m, recommended 50-60m max.
Nitrogen is a component of air that is breathed during diving. Due to the increased pressure underwater, nitrogen can dissolve into body tissues, leading to a condition called nitrogen narcosis or "rapture of the deep," which can impair judgment and coordination at certain depths. Rapid ascent from a dive without proper decompression can also lead to nitrogen bubbles forming in the blood, causing decompression sickness or "the bends."
No longer made but there is a Costco product that is just as good although not compressed into bar form.
Bar XH Air was created in 1974.

Pressure is the physical quantity measured in bar.
Nitrogen is typically obtained by fractional distillation of liquid air, which separates nitrogen from oxygen, argon, and other gases. Alternatively, nitrogen can also be produced by the process of pressure swing adsorption, which involves selectively adsorbing nitrogen gas molecules. Additionally, certain industrial processes such as the Haber-Bosch process can be used to convert atmospheric nitrogen into ammonia, which can then be further processed to obtain pure nitrogen gas.

One liter of gas at 200 bar would expand to approximately 0.2 cubic meters (200 liters) if the pressure is reduced to atmospheric pressure (1 bar).
Of course, for the same function, the bar will be the same. But for a different function, nope.
