Mass is the amount of matter in an object, regardless of its size or volume. It is measured in kilograms (kg) or grams (g). Volume, on the other hand, is the amount of space an object takes up and is measured in liters (l) or milliliters (ml). Mass is a measure of the amount of matter in an object, while volume is a measure of the space that the object occupies. Mass is not affected by gravity, whereas volume is affected by gravity. Mass is an intrinsic property of an object, whereas volume is an extrinsic property of an object. Mass is conserved, meaning it can neither be created nor destroyed, while volume can be changed by changing the shape or size of the object.
