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.
Depending on the composite of the concrete material, it can melt at  different temperatures. When concrete reaches a high enough  temperature such as more than 1000 degrees â¦ Celsius, it can crumble  like sugar.he melting will start with the material that has the lowest temperature melting point unless you allow the system to take a long time and react into other solids first, of course. A ballpark guess of 800-1000Â°C for melting is what I would assume, for various reasons.
