Carbon nanotubes
From the table of pressures and examples of those pressures: "100 GPa - Carbon nanotubes (CNTs)" - what about carbon nanotubes at 100 GPa? Is that the pressure at which they break under force in a particular direction? -- Ke4roh 13:14, 21 Jan 2004 (UTC)
- Added link for tensile strength, to clarify that 100 GPa is not a pressure here. Markus Kuhn 11:06, 30 Apr 2005 (UTC)

Mars atmospheric pressure
This artical says it is 1 kPa. The mars article says it is 0.1 kPa. One of these is wrong. My understanding is that it is 0.7-0.9 kPa which is just slightly above the point where water cannot exist in the liquid phase. Can those who made the wrong example make a correction? -- Terrell Larson
- The Mars article (and other sources I checked) say it is typically 0.75 kPa. The 1 kPa order-of-magnitude figure that is given here seems to be a crude, but easy to memorize, valid, rounded version of that. Markus Kuhn 11:06, 30 Apr 2005 (UTC)
