Dehydration is the excessive loss of fluids in the body. Low levels of calcium and potassium may also cause muscle cramps, since both minerals contribute to healthy muscle function. Low blood supply to your legs and feet can cause cramping in those areas when you exercise, walk, or participate in physical activities.
Physical properties of materials and systems can often be categorized as being either intensive or extensive quantities, according to how the property changes when the size (or extent) of the system changes. According to IUPAC, an intensive property is one whose magnitude is independent of the size of the system.
a physical property is something that keeps the nature of the substance the same - for example if you boil a metal you can always re solidify it, it will be the same. but if y â¦ ou use acid on something or burn it, it is gone forever. you can't undo that and it is a property that changes the matter of the substance
