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.
Salt will melt (become liquid) at 801 degrees Celsius, 1074 degrees Kelvin, 1474 degrees Fahrenheit. It will vaporize at 1465 degrees Celsius, 1738 degrees Kelvin, 2669 degrees Fahrenheit. 801 degree Celsius or 1074 Kelvin It will melt when heated above this temp. It will freeze when cooled below this temp.
