What Is Obesity Hypoventilation Syndrome? Obesity hypoventilation (HI-po-ven-tih-LA-shun) syndrome (OHS) is a breathing disorder that affects some obese people. In OHS, poor breathing results in too much carbon dioxide (hypoventilation) and too little oxygen in the blood (hypoxemia). OHS sometimes is called Pickwickian syndrome.
Click on photo for a larger picture. In the photo above, I am holding two small vials of liquid metal. The vial on the right contains gallium, an element that melts at 29.76Â° Celsius (85.57Â° Fahrenheit). The vial on the left is an alloy that contains gallium, indium, and tin, and melts at -20Â° Celsius (-4Â° Fahrenheit). The gallium is liquid because I had the bottle in my shirt pocket, next to my warm body.
Sulphur is a solid at standard room temperature (which is about 200C). The melting point of sulphur is 1150C and the boiling point is 4450C.ure lead melts at about 327 degrees Celsius or 621 degrees Fahrenheit; it boils at about 1749 degrees Celsius or 3180 Fahrenheit. Room temperature is well below either of the â¦ se so it would be safe to assume that lead would remain a solid in a typical environment.
