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.
There are 3 basic states of matter. These are solid, liquid and gas. The melting point is the temperature at which matter changes completely from solid to liquid, thereby melt â¦ ing. The boiling point is the point at which matter changes completely from liquid to gas, thereby evaporating.itrogen melts at 63.15 K or -210.00 Â°C or -346.00 Â°F. Nitrogen boils at 77.36 K or -195.79 Â°C or -320.3342 Â°F.   Everything more you need can be found by using the l â¦ ink below. It will take you to the Wikipedia post on nitrogen, and knowledge is provided there for free.
