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.
Weight is an extensive physical property because it increases when the object size is getting higher. Difference between Density and Weight. 1. Weight is a measure of the amount of matter in an object, whereas density measures the amount of matter in a unit volume.2. Density is an intensive physical property, whereas weight is an extensive property. 3. Weight is measured in Newtons, whereas density is measured in kilograms per cubic meter.. Weight is a measure of the amount of matter in an object, whereas density measures the amount of matter in a unit volume. 2. Density is an intensive physical property, whereas weight is an extensive property.
