0 Celsius for ais , 100 Celsius for boiling water ?

AI Thread Summary
The discussion centers on the definitions of 0 degrees Celsius for ice and 100 degrees Celsius for boiling water, questioning their universality across different countries. It confirms that these temperature points are valid at normal atmospheric pressure (1 atm). Participants clarify that "ais" was a typographical error for "ice." The conversation highlights the importance of atmospheric conditions in defining these temperature benchmarks. Ultimately, the standard definitions of these temperatures are consistent globally under normal conditions.

0 Celsius for ais , 100 Celsius for boiling water ?

As we know that is common for study.
But anyone know where is origin ?
What i mean is ...is it valid at every country ?

Sorry, what? I literally cannot understand anything you are saying.

Haha sorry...actually i am thinking...
is it all country define 0 Celcius for Ais...and 100 Celsius for boiling water ?
These condition is valid under which condition?
 


Water will boil at 100 degrees Celsius at normal atmospheric pressure (1 atm, ~1 bar, 101KPa).

By "Ais" do you mean air or ice?

Sorry...i type wrong language ..should be ICE
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
