Lupus is an autoimmune disease. This means that your immune system attacks healthy cells and tissues by mistake. This can damage many parts of the body, including the joints, skin, kidneys, heart, lungs, blood vessels, and brain. There are several kinds of lupus.
Freezing, or solidification, is a phase transition in which a liquid turns into a solid when its temperature is lowered below its freezing point. For most substances, the melting and freezing points are the same temperature; however, certain substances possess differing solidâliquid transition temperatures.
Daniel Gabriel Fahrenheit's temperature scale doesn't place 0Â°F at the lowest freezing point of salt water (which occurs at -21.12Â°C, or -6.02Â°F). There are at least three reasons for that. It always takes longer than you think it's going to take, even when you take into account Hofstadter's Law.
